Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646884, here are decompositions:

  • 31 + 8646853 = 8646884
  • 61 + 8646823 = 8646884
  • 67 + 8646817 = 8646884
  • 163 + 8646721 = 8646884
  • 277 + 8646607 = 8646884
  • 313 + 8646571 = 8646884
  • 373 + 8646511 = 8646884
  • 397 + 8646487 = 8646884

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 8,646,884 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 8646884 first appears in π at position 178,405 of the decimal expansion (the 178,405ordinal-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.
