Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159660, here are decompositions:

  • 29 + 159631 = 159660
  • 31 + 159629 = 159660
  • 37 + 159623 = 159660
  • 43 + 159617 = 159660
  • 71 + 159589 = 159660
  • 89 + 159571 = 159660
  • 97 + 159563 = 159660
  • 107 + 159553 = 159660

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 159,660 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 159660 first appears in π at position 175,087 of the decimal expansion (the 175,087ordinal-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.
