Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644584, here are decompositions:

  • 31 + 8644553 = 8644584
  • 73 + 8644511 = 8644584
  • 83 + 8644501 = 8644584
  • 107 + 8644477 = 8644584
  • 127 + 8644457 = 8644584
  • 131 + 8644453 = 8644584
  • 257 + 8644327 = 8644584
  • 283 + 8644301 = 8644584

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 8,644,584 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 8644584 first appears in π at position 892,156 of the decimal expansion (the 892,156ordinal-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.
