Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641338, here are decompositions:

  • 7 + 8641331 = 8641338
  • 11 + 8641327 = 8641338
  • 19 + 8641319 = 8641338
  • 29 + 8641309 = 8641338
  • 37 + 8641301 = 8641338
  • 89 + 8641249 = 8641338
  • 107 + 8641231 = 8641338
  • 127 + 8641211 = 8641338

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 8,641,338 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 8641338 first appears in π at position 257,185 of the decimal expansion (the 257,185ordinal-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.
