Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166524, here are decompositions:

  • 37 + 166487 = 166524
  • 53 + 166471 = 166524
  • 67 + 166457 = 166524
  • 107 + 166417 = 166524
  • 131 + 166393 = 166524
  • 167 + 166357 = 166524
  • 173 + 166351 = 166524
  • 223 + 166301 = 166524

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 166,524 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 166524 first appears in π at position 461,382 of the decimal expansion (the 461,382ordinal-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.
