Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165606, here are decompositions:

  • 5 + 165601 = 165606
  • 17 + 165589 = 165606
  • 19 + 165587 = 165606
  • 37 + 165569 = 165606
  • 47 + 165559 = 165606
  • 53 + 165553 = 165606
  • 73 + 165533 = 165606
  • 79 + 165527 = 165606

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 165,606 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 165606 first appears in π at position 857,318 of the decimal expansion (the 857,318ordinal-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.
