Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990770, here are decompositions:

  • 3 + 990767 = 990770
  • 37 + 990733 = 990770
  • 97 + 990673 = 990770
  • 127 + 990643 = 990770
  • 139 + 990631 = 990770
  • 181 + 990589 = 990770
  • 211 + 990559 = 990770
  • 223 + 990547 = 990770

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 990,770 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 990770 first appears in π at position 831,442 of the decimal expansion (the 831,442ordinal-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.
