Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639038, here are decompositions:

  • 11 + 8639027 = 8639038
  • 41 + 8638997 = 8639038
  • 47 + 8638991 = 8639038
  • 71 + 8638967 = 8639038
  • 101 + 8638937 = 8639038
  • 311 + 8638727 = 8639038
  • 347 + 8638691 = 8639038
  • 521 + 8638517 = 8639038

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 8,639,038 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 8639038 first appears in π at position 764,928 of the decimal expansion (the 764,928ordinal-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.
