Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687308, here are decompositions:

  • 5 + 8687303 = 8687308
  • 17 + 8687291 = 8687308
  • 59 + 8687249 = 8687308
  • 101 + 8687207 = 8687308
  • 137 + 8687171 = 8687308
  • 167 + 8687141 = 8687308
  • 191 + 8687117 = 8687308
  • 239 + 8687069 = 8687308

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 8,687,308 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 8687308 first appears in π at position 98,264 of the decimal expansion (the 98,264ordinal-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.
