Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990306, here are decompositions:

  • 13 + 990293 = 990306
  • 17 + 990289 = 990306
  • 19 + 990287 = 990306
  • 29 + 990277 = 990306
  • 47 + 990259 = 990306
  • 67 + 990239 = 990306
  • 127 + 990179 = 990306
  • 137 + 990169 = 990306

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 990,306 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 990306 first appears in π at position 343,965 of the decimal expansion (the 343,965ordinal-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.
