Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991832, here are decompositions:

  • 109 + 991723 = 991832
  • 139 + 991693 = 991832
  • 181 + 991651 = 991832
  • 199 + 991633 = 991832
  • 211 + 991621 = 991832
  • 229 + 991603 = 991832
  • 349 + 991483 = 991832
  • 379 + 991453 = 991832

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 991,832 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 991832 first appears in π at position 494,444 of the decimal expansion (the 494,444ordinal-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.
