Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693638, here are decompositions:

  • 11 + 8693627 = 8693638
  • 71 + 8693567 = 8693638
  • 89 + 8693549 = 8693638
  • 179 + 8693459 = 8693638
  • 197 + 8693441 = 8693638
  • 251 + 8693387 = 8693638
  • 257 + 8693381 = 8693638
  • 269 + 8693369 = 8693638

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 8,693,638 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 8693638 first appears in π at position 620,587 of the decimal expansion (the 620,587ordinal-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.
