Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999740, here are decompositions:

  • 13 + 999727 = 999740
  • 19 + 999721 = 999740
  • 73 + 999667 = 999740
  • 109 + 999631 = 999740
  • 127 + 999613 = 999740
  • 199 + 999541 = 999740
  • 211 + 999529 = 999740
  • 241 + 999499 = 999740

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 999,740 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 999740 first appears in π at position 49,135 of the decimal expansion (the 49,135ordinal-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.
