Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990192, here are decompositions:

  • 11 + 990181 = 990192
  • 13 + 990179 = 990192
  • 23 + 990169 = 990192
  • 29 + 990163 = 990192
  • 41 + 990151 = 990192
  • 139 + 990053 = 990192
  • 149 + 990043 = 990192
  • 179 + 990013 = 990192

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 990,192 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 990192 first appears in π at position 238,398 of the decimal expansion (the 238,398ordinal-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.
