Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162730, here are decompositions:

  • 3 + 162727 = 162730
  • 17 + 162713 = 162730
  • 47 + 162683 = 162730
  • 53 + 162677 = 162730
  • 59 + 162671 = 162730
  • 89 + 162641 = 162730
  • 101 + 162629 = 162730
  • 107 + 162623 = 162730

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 162,730 and was likely granted around 1874.

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

Position in π

The digit sequence 162730 first appears in π at position 837,954 of the decimal expansion (the 837,954ordinal-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.
