Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166382, here are decompositions:

  • 19 + 166363 = 166382
  • 31 + 166351 = 166382
  • 79 + 166303 = 166382
  • 109 + 166273 = 166382
  • 163 + 166219 = 166382
  • 193 + 166189 = 166382
  • 199 + 166183 = 166382
  • 283 + 166099 = 166382

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 166,382 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 166382 first appears in π at position 252,669 of the decimal expansion (the 252,669ordinal-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.
