Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990744, here are decompositions:

  • 11 + 990733 = 990744
  • 37 + 990707 = 990744
  • 71 + 990673 = 990744
  • 101 + 990643 = 990744
  • 107 + 990637 = 990744
  • 113 + 990631 = 990744
  • 151 + 990593 = 990744
  • 197 + 990547 = 990744

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 990,744 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 990744 first appears in π at position 354,267 of the decimal expansion (the 354,267ordinal-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.
