Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663168, here are decompositions:

  • 67 + 8663101 = 8663168
  • 79 + 8663089 = 8663168
  • 97 + 8663071 = 8663168
  • 181 + 8662987 = 8663168
  • 229 + 8662939 = 8663168
  • 277 + 8662891 = 8663168
  • 337 + 8662831 = 8663168
  • 421 + 8662747 = 8663168

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 8,663,168 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 8663168 first appears in π at position 245,489 of the decimal expansion (the 245,489ordinal-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.
