Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689238, here are decompositions:

  • 97 + 8689141 = 8689238
  • 109 + 8689129 = 8689238
  • 127 + 8689111 = 8689238
  • 199 + 8689039 = 8689238
  • 241 + 8688997 = 8689238
  • 277 + 8688961 = 8689238
  • 409 + 8688829 = 8689238
  • 421 + 8688817 = 8689238

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 8,689,238 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 8689238 first appears in π at position 543,470 of the decimal expansion (the 543,470ordinal-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.
