Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990672, here are decompositions:

  • 29 + 990643 = 990672
  • 41 + 990631 = 990672
  • 73 + 990599 = 990672
  • 79 + 990593 = 990672
  • 83 + 990589 = 990672
  • 113 + 990559 = 990672
  • 149 + 990523 = 990672
  • 283 + 990389 = 990672

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 990,672 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 990672 first appears in π at position 925,280 of the decimal expansion (the 925,280ordinal-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.
