Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617864, here are decompositions:

  • 41 + 8617823 = 8617864
  • 317 + 8617547 = 8617864
  • 467 + 8617397 = 8617864
  • 491 + 8617373 = 8617864
  • 503 + 8617361 = 8617864
  • 587 + 8617277 = 8617864
  • 653 + 8617211 = 8617864
  • 677 + 8617187 = 8617864

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,617,864 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8617864 first appears in π at position 416,837 of the decimal expansion (the 416,837ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
