Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637458, here are decompositions:

  • 7 + 8637451 = 8637458
  • 31 + 8637427 = 8637458
  • 79 + 8637379 = 8637458
  • 139 + 8637319 = 8637458
  • 157 + 8637301 = 8637458
  • 211 + 8637247 = 8637458
  • 307 + 8637151 = 8637458
  • 367 + 8637091 = 8637458

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 8,637,458 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 8637458 first appears in π at position 768,454 of the decimal expansion (the 768,454ordinal-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.
