Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991514, here are decompositions:

  • 3 + 991511 = 991514
  • 31 + 991483 = 991514
  • 61 + 991453 = 991514
  • 67 + 991447 = 991514
  • 127 + 991387 = 991514
  • 157 + 991357 = 991514
  • 241 + 991273 = 991514
  • 313 + 991201 = 991514

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 991,514 and was likely granted around 1911.

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

Position in π

The digit sequence 991514 first appears in π at position 852,515 of the decimal expansion (the 852,515ordinal-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.
