Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712438, here are decompositions:

  • 17 + 8712421 = 8712438
  • 41 + 8712397 = 8712438
  • 67 + 8712371 = 8712438
  • 71 + 8712367 = 8712438
  • 89 + 8712349 = 8712438
  • 101 + 8712337 = 8712438
  • 127 + 8712311 = 8712438
  • 131 + 8712307 = 8712438

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 8,712,438 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 8712438 first appears in π at position 70,832 of the decimal expansion (the 70,832ordinal-suffix:nd 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.
