Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998730, here are decompositions:

  • 13 + 998717 = 998730
  • 41 + 998689 = 998730
  • 43 + 998687 = 998730
  • 79 + 998651 = 998730
  • 97 + 998633 = 998730
  • 101 + 998629 = 998730
  • 107 + 998623 = 998730
  • 113 + 998617 = 998730

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 998,730 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 998730 first appears in π at position 395,874 of the decimal expansion (the 395,874ordinal-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.
