Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669904, here are decompositions:

  • 7 + 8669897 = 8669904
  • 11 + 8669893 = 8669904
  • 43 + 8669861 = 8669904
  • 73 + 8669831 = 8669904
  • 83 + 8669821 = 8669904
  • 127 + 8669777 = 8669904
  • 137 + 8669767 = 8669904
  • 233 + 8669671 = 8669904

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 8,669,904 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 8669904 first appears in π at position 625,112 of the decimal expansion (the 625,112ordinal-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.
