Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545742, here are decompositions:

  • 11 + 545731 = 545742
  • 19 + 545723 = 545742
  • 31 + 545711 = 545742
  • 79 + 545663 = 545742
  • 101 + 545641 = 545742
  • 163 + 545579 = 545742
  • 191 + 545551 = 545742
  • 193 + 545549 = 545742

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 545,742 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 545742 first appears in π at position 242,952 of the decimal expansion (the 242,952ordinal-suffix:nd 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.
