Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687258, here are decompositions:

  • 31 + 8687227 = 8687258
  • 61 + 8687197 = 8687258
  • 109 + 8687149 = 8687258
  • 127 + 8687131 = 8687258
  • 277 + 8686981 = 8687258
  • 571 + 8686687 = 8687258
  • 607 + 8686651 = 8687258
  • 691 + 8686567 = 8687258

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 8,687,258 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 8687258 first appears in π at position 171,080 of the decimal expansion (the 171,080ordinal-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.
