Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979940, here are decompositions:

  • 19 + 979921 = 979940
  • 67 + 979873 = 979940
  • 109 + 979831 = 979940
  • 193 + 979747 = 979940
  • 223 + 979717 = 979940
  • 373 + 979567 = 979940
  • 397 + 979543 = 979940
  • 421 + 979519 = 979940

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 979,940 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 979940 first appears in π at position 639,152 of the decimal expansion (the 639,152ordinal-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.
