Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981976, here are decompositions:

  • 29 + 981947 = 981976
  • 89 + 981887 = 981976
  • 167 + 981809 = 981976
  • 179 + 981797 = 981976
  • 263 + 981713 = 981976
  • 269 + 981707 = 981976
  • 293 + 981683 = 981976
  • 353 + 981623 = 981976

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 981,976 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 981976 first appears in π at position 650,891 of the decimal expansion (the 650,891ordinal-suffix:st 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.
