Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163018, here are decompositions:

  • 29 + 162989 = 163018
  • 47 + 162971 = 163018
  • 71 + 162947 = 163018
  • 101 + 162917 = 163018
  • 137 + 162881 = 163018
  • 179 + 162839 = 163018
  • 197 + 162821 = 163018
  • 227 + 162791 = 163018

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 163,018 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 163018 first appears in π at position 187,895 of the decimal expansion (the 187,895ordinal-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.
