Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643634, here are decompositions:

  • 3 + 8643631 = 8643634
  • 47 + 8643587 = 8643634
  • 71 + 8643563 = 8643634
  • 107 + 8643527 = 8643634
  • 113 + 8643521 = 8643634
  • 191 + 8643443 = 8643634
  • 317 + 8643317 = 8643634
  • 347 + 8643287 = 8643634

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 8,643,634 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 8643634 first appears in π at position 873,563 of the decimal expansion (the 873,563ordinal-suffix:rd 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.
