Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669590, here are decompositions:

  • 47 + 8669543 = 8669590
  • 89 + 8669501 = 8669590
  • 101 + 8669489 = 8669590
  • 107 + 8669483 = 8669590
  • 113 + 8669477 = 8669590
  • 173 + 8669417 = 8669590
  • 179 + 8669411 = 8669590
  • 191 + 8669399 = 8669590

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 8,669,590 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 8669590 first appears in π at position 91,360 of the decimal expansion (the 91,360ordinal-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.
