Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998930, here are decompositions:

  • 3 + 998927 = 998930
  • 13 + 998917 = 998930
  • 73 + 998857 = 998930
  • 151 + 998779 = 998930
  • 181 + 998749 = 998930
  • 193 + 998737 = 998930
  • 241 + 998689 = 998930
  • 277 + 998653 = 998930

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 998,930 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 998930 first appears in π at position 140,163 of the decimal expansion (the 140,163ordinal-suffix:rd 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.
