Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166608, here are decompositions:

  • 5 + 166603 = 166608
  • 7 + 166601 = 166608
  • 11 + 166597 = 166608
  • 37 + 166571 = 166608
  • 41 + 166567 = 166608
  • 47 + 166561 = 166608
  • 67 + 166541 = 166608
  • 137 + 166471 = 166608

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 166,608 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 166608 first appears in π at position 23,510 of the decimal expansion (the 23,510ordinal-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.
