Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712538, here are decompositions:

  • 5 + 8712533 = 8712538
  • 41 + 8712497 = 8712538
  • 47 + 8712491 = 8712538
  • 167 + 8712371 = 8712538
  • 227 + 8712311 = 8712538
  • 251 + 8712287 = 8712538
  • 257 + 8712281 = 8712538
  • 269 + 8712269 = 8712538

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 8,712,538 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 8712538 first appears in π at position 53,581 of the decimal expansion (the 53,581ordinal-suffix:st 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.
