Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998808, here are decompositions:

  • 29 + 998779 = 998808
  • 59 + 998749 = 998808
  • 71 + 998737 = 998808
  • 127 + 998681 = 998808
  • 157 + 998651 = 998808
  • 179 + 998629 = 998808
  • 191 + 998617 = 998808
  • 257 + 998551 = 998808

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 998,808 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 998808 first appears in π at position 675,983 of the decimal expansion (the 675,983ordinal-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.
