Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545844, here are decompositions:

  • 17 + 545827 = 545844
  • 53 + 545791 = 545844
  • 71 + 545773 = 545844
  • 97 + 545747 = 545844
  • 113 + 545731 = 545844
  • 181 + 545663 = 545844
  • 193 + 545651 = 545844
  • 197 + 545647 = 545844

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 545,844 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 545844 first appears in π at position 215,123 of the decimal expansion (the 215,123ordinal-suffix:rd 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.
