Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961380, here are decompositions:

  • 41 + 961339 = 961380
  • 61 + 961319 = 961380
  • 67 + 961313 = 961380
  • 97 + 961283 = 961380
  • 103 + 961277 = 961380
  • 107 + 961273 = 961380
  • 137 + 961243 = 961380
  • 139 + 961241 = 961380

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 961,380 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 961380 first appears in π at position 24,496 of the decimal expansion (the 24,496ordinal-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.
