Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697420, here are decompositions:

  • 13 + 8697407 = 8697420
  • 31 + 8697389 = 8697420
  • 41 + 8697379 = 8697420
  • 107 + 8697313 = 8697420
  • 157 + 8697263 = 8697420
  • 167 + 8697253 = 8697420
  • 181 + 8697239 = 8697420
  • 257 + 8697163 = 8697420

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 8,697,420 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 8697420 first appears in π at position 503,965 of the decimal expansion (the 503,965ordinal-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.
