Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990572, here are decompositions:

  • 13 + 990559 = 990572
  • 43 + 990529 = 990572
  • 61 + 990511 = 990572
  • 103 + 990469 = 990572
  • 109 + 990463 = 990572
  • 211 + 990361 = 990572
  • 223 + 990349 = 990572
  • 241 + 990331 = 990572

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 990,572 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 990572 first appears in π at position 247,936 of the decimal expansion (the 247,936ordinal-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.
