Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166244, here are decompositions:

  • 7 + 166237 = 166244
  • 37 + 166207 = 166244
  • 61 + 166183 = 166244
  • 97 + 166147 = 166244
  • 163 + 166081 = 166244
  • 181 + 166063 = 166244
  • 223 + 166021 = 166244
  • 283 + 165961 = 166244

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 166,244 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 166244 first appears in π at position 126,542 of the decimal expansion (the 126,542ordinal-suffix:nd 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.
