Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631994, here are decompositions:

  • 17 + 8631977 = 8631994
  • 83 + 8631911 = 8631994
  • 101 + 8631893 = 8631994
  • 113 + 8631881 = 8631994
  • 191 + 8631803 = 8631994
  • 251 + 8631743 = 8631994
  • 257 + 8631737 = 8631994
  • 281 + 8631713 = 8631994

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 8,631,994 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 8631994 first appears in π at position 567,582 of the decimal expansion (the 567,582ordinal-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.
