Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945780, here are decompositions:

  • 13 + 945767 = 945780
  • 41 + 945739 = 945780
  • 47 + 945733 = 945780
  • 79 + 945701 = 945780
  • 103 + 945677 = 945780
  • 107 + 945673 = 945780
  • 109 + 945671 = 945780
  • 149 + 945631 = 945780

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 945,780 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 945780 first appears in π at position 216,254 of the decimal expansion (the 216,254ordinal-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.
