Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980986, here are decompositions:

  • 23 + 980963 = 980986
  • 29 + 980957 = 980986
  • 89 + 980897 = 980986
  • 257 + 980729 = 980986
  • 269 + 980717 = 980986
  • 563 + 980423 = 980986
  • 569 + 980417 = 980986
  • 593 + 980393 = 980986

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 980,986 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 980986 first appears in π at position 638,341 of the decimal expansion (the 638,341ordinal-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.
