Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990970, here are decompositions:

  • 3 + 990967 = 990970
  • 17 + 990953 = 990970
  • 47 + 990923 = 990970
  • 53 + 990917 = 990970
  • 83 + 990887 = 990970
  • 89 + 990881 = 990970
  • 173 + 990797 = 990970
  • 251 + 990719 = 990970

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 990,970 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 990970 first appears in π at position 254,277 of the decimal expansion (the 254,277ordinal-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.
