Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164488, here are decompositions:

  • 11 + 164477 = 164488
  • 17 + 164471 = 164488
  • 41 + 164447 = 164488
  • 59 + 164429 = 164488
  • 101 + 164387 = 164488
  • 131 + 164357 = 164488
  • 167 + 164321 = 164488
  • 179 + 164309 = 164488

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 164,488 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 164488 first appears in π at position 128,681 of the decimal expansion (the 128,681ordinal-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.
