Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998684, here are decompositions:

  • 3 + 998681 = 998684
  • 31 + 998653 = 998684
  • 61 + 998623 = 998684
  • 67 + 998617 = 998684
  • 157 + 998527 = 998684
  • 241 + 998443 = 998684
  • 307 + 998377 = 998684
  • 331 + 998353 = 998684

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 998,684 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 998684 first appears in π at position 982,070 of the decimal expansion (the 982,070ordinal-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.
