Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166268, here are decompositions:

  • 31 + 166237 = 166268
  • 61 + 166207 = 166268
  • 79 + 166189 = 166268
  • 241 + 166027 = 166268
  • 307 + 165961 = 166268
  • 337 + 165931 = 166268
  • 367 + 165901 = 166268
  • 439 + 165829 = 166268

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 166,268 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 166268 first appears in π at position 302,553 of the decimal expansion (the 302,553ordinal-suffix:rd 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.
