Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644226, here are decompositions:

  • 13 + 8644213 = 8644226
  • 79 + 8644147 = 8644226
  • 103 + 8644123 = 8644226
  • 229 + 8643997 = 8644226
  • 307 + 8643919 = 8644226
  • 337 + 8643889 = 8644226
  • 439 + 8643787 = 8644226
  • 607 + 8643619 = 8644226

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 8,644,226 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 8644226 first appears in π at position 465,559 of the decimal expansion (the 465,559ordinal-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.
