Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961722, here are decompositions:

  • 19 + 961703 = 961722
  • 31 + 961691 = 961722
  • 43 + 961679 = 961722
  • 59 + 961663 = 961722
  • 61 + 961661 = 961722
  • 79 + 961643 = 961722
  • 89 + 961633 = 961722
  • 103 + 961619 = 961722

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 961,722 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 961722 first appears in π at position 618,668 of the decimal expansion (the 618,668ordinal-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.
