Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947986, here are decompositions:

  • 23 + 947963 = 947986
  • 59 + 947927 = 947986
  • 113 + 947873 = 947986
  • 167 + 947819 = 947986
  • 233 + 947753 = 947986
  • 239 + 947747 = 947986
  • 257 + 947729 = 947986
  • 359 + 947627 = 947986

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 947,986 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 947986 first appears in π at position 442,414 of the decimal expansion (the 442,414ordinal-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.
