Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998830, here are decompositions:

  • 11 + 998819 = 998830
  • 17 + 998813 = 998830
  • 71 + 998759 = 998830
  • 113 + 998717 = 998830
  • 149 + 998681 = 998830
  • 179 + 998651 = 998830
  • 197 + 998633 = 998830
  • 269 + 998561 = 998830

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 998,830 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 998830 first appears in π at position 222,522 of the decimal expansion (the 222,522ordinal-suffix:nd 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.
