Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990190, here are decompositions:

  • 11 + 990179 = 990190
  • 53 + 990137 = 990190
  • 137 + 990053 = 990190
  • 167 + 990023 = 990190
  • 191 + 989999 = 990190
  • 239 + 989951 = 990190
  • 251 + 989939 = 990190
  • 269 + 989921 = 990190

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 990,190 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 990190 first appears in π at position 509,042 of the decimal expansion (the 509,042ordinal-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.
