Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545812, here are decompositions:

  • 23 + 545789 = 545812
  • 53 + 545759 = 545812
  • 89 + 545723 = 545812
  • 101 + 545711 = 545812
  • 149 + 545663 = 545812
  • 191 + 545621 = 545812
  • 233 + 545579 = 545812
  • 263 + 545549 = 545812

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 545,812 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 545812 first appears in π at position 463,749 of the decimal expansion (the 463,749ordinal-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.
