Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671864, here are decompositions:

  • 53 + 8671811 = 8671864
  • 167 + 8671697 = 8671864
  • 233 + 8671631 = 8671864
  • 281 + 8671583 = 8671864
  • 347 + 8671517 = 8671864
  • 353 + 8671511 = 8671864
  • 401 + 8671463 = 8671864
  • 503 + 8671361 = 8671864

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 8,671,864 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 8671864 first appears in π at position 818,582 of the decimal expansion (the 818,582ordinal-suffix:nd 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.
