Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163964, here are decompositions:

  • 37 + 163927 = 163964
  • 103 + 163861 = 163964
  • 193 + 163771 = 163964
  • 211 + 163753 = 163964
  • 223 + 163741 = 163964
  • 331 + 163633 = 163964
  • 337 + 163627 = 163964
  • 397 + 163567 = 163964

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 163,964 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 163964 first appears in π at position 836,741 of the decimal expansion (the 836,741ordinal-suffix:st 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.
