Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687356, here are decompositions:

  • 47 + 8687309 = 8687356
  • 53 + 8687303 = 8687356
  • 107 + 8687249 = 8687356
  • 149 + 8687207 = 8687356
  • 173 + 8687183 = 8687356
  • 239 + 8687117 = 8687356
  • 263 + 8687093 = 8687356
  • 269 + 8687087 = 8687356

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 8,687,356 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 8687356 first appears in π at position 752,858 of the decimal expansion (the 752,858ordinal-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.
