Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990738, here are decompositions:

  • 5 + 990733 = 990738
  • 19 + 990719 = 990738
  • 31 + 990707 = 990738
  • 101 + 990637 = 990738
  • 107 + 990631 = 990738
  • 139 + 990599 = 990738
  • 149 + 990589 = 990738
  • 179 + 990559 = 990738

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 990,738 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 990738 first appears in π at position 45,713 of the decimal expansion (the 45,713ordinal-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.
