Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945580, here are decompositions:

  • 3 + 945577 = 945580
  • 59 + 945521 = 945580
  • 101 + 945479 = 945580
  • 107 + 945473 = 945580
  • 149 + 945431 = 945580
  • 191 + 945389 = 945580
  • 239 + 945341 = 945580
  • 347 + 945233 = 945580

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 945,580 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 945580 first appears in π at position 34,647 of the decimal expansion (the 34,647ordinal-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.
