Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998100, here are decompositions:

  • 17 + 998083 = 998100
  • 23 + 998077 = 998100
  • 29 + 998071 = 998100
  • 31 + 998069 = 998100
  • 71 + 998029 = 998100
  • 73 + 998027 = 998100
  • 83 + 998017 = 998100
  • 109 + 997991 = 998100

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 998,100 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 998100 first appears in π at position 119,498 of the decimal expansion (the 119,498ordinal-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.
