Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164580, here are decompositions:

  • 11 + 164569 = 164580
  • 67 + 164513 = 164580
  • 103 + 164477 = 164580
  • 109 + 164471 = 164580
  • 131 + 164449 = 164580
  • 137 + 164443 = 164580
  • 149 + 164431 = 164580
  • 151 + 164429 = 164580

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 164,580 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 164580 first appears in π at position 294,527 of the decimal expansion (the 294,527ordinal-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.
