Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640422, here are decompositions:

  • 3 + 8640419 = 8640422
  • 13 + 8640409 = 8640422
  • 31 + 8640391 = 8640422
  • 73 + 8640349 = 8640422
  • 163 + 8640259 = 8640422
  • 181 + 8640241 = 8640422
  • 211 + 8640211 = 8640422
  • 313 + 8640109 = 8640422

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 8,640,422 and was likely granted around 2014.

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

Position in π

The digit sequence 8640422 first appears in π at position 937,228 of the decimal expansion (the 937,228ordinal-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.
