Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166772, here are decompositions:

  • 31 + 166741 = 166772
  • 79 + 166693 = 166772
  • 103 + 166669 = 166772
  • 163 + 166609 = 166772
  • 211 + 166561 = 166772
  • 373 + 166399 = 166772
  • 379 + 166393 = 166772
  • 409 + 166363 = 166772

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 166,772 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 166772 first appears in π at position 451,606 of the decimal expansion (the 451,606ordinal-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.
