Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545646, here are decompositions:

  • 5 + 545641 = 545646
  • 29 + 545617 = 545646
  • 37 + 545609 = 545646
  • 47 + 545599 = 545646
  • 67 + 545579 = 545646
  • 97 + 545549 = 545646
  • 103 + 545543 = 545646
  • 113 + 545533 = 545646

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 545,646 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 545646 first appears in π at position 774,451 of the decimal expansion (the 774,451ordinal-suffix:st 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.
