Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603856, here are decompositions:

  • 13 + 8603843 = 8603856
  • 17 + 8603839 = 8603856
  • 43 + 8603813 = 8603856
  • 59 + 8603797 = 8603856
  • 89 + 8603767 = 8603856
  • 103 + 8603753 = 8603856
  • 127 + 8603729 = 8603856
  • 167 + 8603689 = 8603856

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 8,603,856 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8603856 first appears in π at position 981,706 of the decimal expansion (the 981,706ordinal-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.
