Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993690, here are decompositions:

  • 7 + 993683 = 993690
  • 11 + 993679 = 993690
  • 43 + 993647 = 993690
  • 73 + 993617 = 993690
  • 79 + 993611 = 993690
  • 101 + 993589 = 993690
  • 149 + 993541 = 993690
  • 163 + 993527 = 993690

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 993,690 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 993690 first appears in π at position 290,729 of the decimal expansion (the 290,729ordinal-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.
