Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545942, here are decompositions:

  • 3 + 545939 = 545942
  • 13 + 545929 = 545942
  • 31 + 545911 = 545942
  • 43 + 545899 = 545942
  • 79 + 545863 = 545942
  • 151 + 545791 = 545942
  • 193 + 545749 = 545942
  • 211 + 545731 = 545942

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 545,942 and was likely granted around 1895.

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

Position in π

The digit sequence 545942 first appears in π at position 750,398 of the decimal expansion (the 750,398ordinal-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.
