Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639974, here are decompositions:

  • 23 + 8639951 = 8639974
  • 53 + 8639921 = 8639974
  • 71 + 8639903 = 8639974
  • 137 + 8639837 = 8639974
  • 227 + 8639747 = 8639974
  • 263 + 8639711 = 8639974
  • 311 + 8639663 = 8639974
  • 383 + 8639591 = 8639974

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 8,639,974 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 8639974 first appears in π at position 377,804 of the decimal expansion (the 377,804ordinal-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.
