Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990368, here are decompositions:

  • 7 + 990361 = 990368
  • 19 + 990349 = 990368
  • 37 + 990331 = 990368
  • 61 + 990307 = 990368
  • 79 + 990289 = 990368
  • 109 + 990259 = 990368
  • 157 + 990211 = 990368
  • 199 + 990169 = 990368

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 990,368 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 990368 first appears in π at position 448,349 of the decimal expansion (the 448,349ordinal-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.
