Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545900, here are decompositions:

  • 7 + 545893 = 545900
  • 37 + 545863 = 545900
  • 73 + 545827 = 545900
  • 109 + 545791 = 545900
  • 127 + 545773 = 545900
  • 151 + 545749 = 545900
  • 283 + 545617 = 545900
  • 349 + 545551 = 545900

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 545,900 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 545900 first appears in π at position 176,863 of the decimal expansion (the 176,863ordinal-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.
