Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689970, here are decompositions:

  • 13 + 8689957 = 8689970
  • 127 + 8689843 = 8689970
  • 193 + 8689777 = 8689970
  • 241 + 8689729 = 8689970
  • 283 + 8689687 = 8689970
  • 313 + 8689657 = 8689970
  • 379 + 8689591 = 8689970
  • 397 + 8689573 = 8689970

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 8,689,970 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 8689970 first appears in π at position 409,209 of the decimal expansion (the 409,209ordinal-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.
