Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182742, here are decompositions:

  • 29 + 182713 = 182742
  • 31 + 182711 = 182742
  • 41 + 182701 = 182742
  • 61 + 182681 = 182742
  • 83 + 182659 = 182742
  • 89 + 182653 = 182742
  • 101 + 182641 = 182742
  • 103 + 182639 = 182742

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 182,742 and was likely granted around 1875.

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

Position in π

The digit sequence 182742 first appears in π at position 838,892 of the decimal expansion (the 838,892ordinal-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.
