Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998790, here are decompositions:

  • 11 + 998779 = 998790
  • 31 + 998759 = 998790
  • 41 + 998749 = 998790
  • 47 + 998743 = 998790
  • 53 + 998737 = 998790
  • 73 + 998717 = 998790
  • 101 + 998689 = 998790
  • 103 + 998687 = 998790

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 998,790 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 998790 first appears in π at position 97,045 of the decimal expansion (the 97,045ordinal-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.
