Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981996, here are decompositions:

  • 13 + 981983 = 981996
  • 17 + 981979 = 981996
  • 47 + 981949 = 981996
  • 83 + 981913 = 981996
  • 107 + 981889 = 981996
  • 109 + 981887 = 981996
  • 173 + 981823 = 981996
  • 179 + 981817 = 981996

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 981,996 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 981996 first appears in π at position 487,094 of the decimal expansion (the 487,094ordinal-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.
