Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657402, here are decompositions:

  • 79 + 8657323 = 8657402
  • 163 + 8657239 = 8657402
  • 181 + 8657221 = 8657402
  • 241 + 8657161 = 8657402
  • 349 + 8657053 = 8657402
  • 463 + 8656939 = 8657402
  • 499 + 8656903 = 8657402
  • 571 + 8656831 = 8657402

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 8,657,402 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 8657402 first appears in π at position 753,523 of the decimal expansion (the 753,523ordinal-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.
