Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663128, here are decompositions:

  • 11 + 8663117 = 8663128
  • 29 + 8663099 = 8663128
  • 137 + 8662991 = 8663128
  • 239 + 8662889 = 8663128
  • 269 + 8662859 = 8663128
  • 317 + 8662811 = 8663128
  • 359 + 8662769 = 8663128
  • 479 + 8662649 = 8663128

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 8,663,128 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 8663128 first appears in π at position 347,242 of the decimal expansion (the 347,242ordinal-suffix:nd 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.
