Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943642, here are decompositions:

  • 5 + 943637 = 943642
  • 41 + 943601 = 943642
  • 53 + 943589 = 943642
  • 71 + 943571 = 943642
  • 101 + 943541 = 943642
  • 131 + 943511 = 943642
  • 233 + 943409 = 943642
  • 239 + 943403 = 943642

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 943,642 and was likely granted around 1909.

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

Position in π

The digit sequence 943642 first appears in π at position 822,178 of the decimal expansion (the 822,178ordinal-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.
