Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643270, here are decompositions:

  • 47 + 8643223 = 8643270
  • 59 + 8643211 = 8643270
  • 61 + 8643209 = 8643270
  • 71 + 8643199 = 8643270
  • 73 + 8643197 = 8643270
  • 89 + 8643181 = 8643270
  • 127 + 8643143 = 8643270
  • 137 + 8643133 = 8643270

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 8,643,270 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 8643270 first appears in π at position 968,485 of the decimal expansion (the 968,485ordinal-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.
