Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639382, here are decompositions:

  • 19 + 8639363 = 8639382
  • 83 + 8639299 = 8639382
  • 109 + 8639273 = 8639382
  • 131 + 8639251 = 8639382
  • 163 + 8639219 = 8639382
  • 211 + 8639171 = 8639382
  • 229 + 8639153 = 8639382
  • 233 + 8639149 = 8639382

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 8,639,382 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 8639382 first appears in π at position 964,823 of the decimal expansion (the 964,823ordinal-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.
