Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164140, here are decompositions:

  • 23 + 164117 = 164140
  • 47 + 164093 = 164140
  • 83 + 164057 = 164140
  • 89 + 164051 = 164140
  • 101 + 164039 = 164140
  • 149 + 163991 = 164140
  • 167 + 163973 = 164140
  • 239 + 163901 = 164140

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 164,140 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 164140 first appears in π at position 683,410 of the decimal expansion (the 683,410ordinal-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.
