Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166630, here are decompositions:

  • 3 + 166627 = 166630
  • 11 + 166619 = 166630
  • 17 + 166613 = 166630
  • 29 + 166601 = 166630
  • 59 + 166571 = 166630
  • 89 + 166541 = 166630
  • 173 + 166457 = 166630
  • 227 + 166403 = 166630

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 166,630 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 166630 first appears in π at position 368,118 of the decimal expansion (the 368,118ordinal-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.
