Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164000, here are decompositions:

  • 3 + 163997 = 164000
  • 7 + 163993 = 164000
  • 13 + 163987 = 164000
  • 19 + 163981 = 164000
  • 73 + 163927 = 164000
  • 139 + 163861 = 164000
  • 181 + 163819 = 164000
  • 211 + 163789 = 164000

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 164,000 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 164000 first appears in π at position 305,774 of the decimal expansion (the 305,774ordinal-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.
