Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701420, here are decompositions:

  • 11 + 8701409 = 8701420
  • 17 + 8701403 = 8701420
  • 29 + 8701391 = 8701420
  • 53 + 8701367 = 8701420
  • 71 + 8701349 = 8701420
  • 131 + 8701289 = 8701420
  • 149 + 8701271 = 8701420
  • 227 + 8701193 = 8701420

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 8,701,420 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 8701420 first appears in π at position 583,116 of the decimal expansion (the 583,116ordinal-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.
