Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166454, here are decompositions:

  • 37 + 166417 = 166454
  • 61 + 166393 = 166454
  • 97 + 166357 = 166454
  • 103 + 166351 = 166454
  • 151 + 166303 = 166454
  • 157 + 166297 = 166454
  • 181 + 166273 = 166454
  • 271 + 166183 = 166454

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 166,454 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 166454 first appears in π at position 51,862 of the decimal expansion (the 51,862ordinal-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.
