Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162370, here are decompositions:

  • 11 + 162359 = 162370
  • 83 + 162287 = 162370
  • 101 + 162269 = 162370
  • 107 + 162263 = 162370
  • 113 + 162257 = 162370
  • 149 + 162221 = 162370
  • 227 + 162143 = 162370
  • 251 + 162119 = 162370

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 162,370 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 162370 first appears in π at position 450,212 of the decimal expansion (the 450,212ordinal-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.
