Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142746, here are decompositions:

  • 13 + 142733 = 142746
  • 47 + 142699 = 142746
  • 73 + 142673 = 142746
  • 89 + 142657 = 142746
  • 127 + 142619 = 142746
  • 137 + 142609 = 142746
  • 139 + 142607 = 142746
  • 157 + 142589 = 142746

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 142,746 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 142746 first appears in π at position 922,298 of the decimal expansion (the 922,298ordinal-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.
