Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617664, here are decompositions:

  • 37 + 8617627 = 8617664
  • 103 + 8617561 = 8617664
  • 151 + 8617513 = 8617664
  • 283 + 8617381 = 8617664
  • 331 + 8617333 = 8617664
  • 337 + 8617327 = 8617664
  • 373 + 8617291 = 8617664
  • 457 + 8617207 = 8617664

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 8,617,664 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 8617664 first appears in π at position 851,440 of the decimal expansion (the 851,440ordinal-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.
