Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663938, here are decompositions:

  • 131 + 8663807 = 8663938
  • 197 + 8663741 = 8663938
  • 251 + 8663687 = 8663938
  • 317 + 8663621 = 8663938
  • 359 + 8663579 = 8663938
  • 401 + 8663537 = 8663938
  • 419 + 8663519 = 8663938
  • 431 + 8663507 = 8663938

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 8,663,938 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 8663938 first appears in π at position 9,556 of the decimal expansion (the 9,556ordinal-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.
