Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160858, here are decompositions:

  • 17 + 160841 = 160858
  • 29 + 160829 = 160858
  • 41 + 160817 = 160858
  • 101 + 160757 = 160858
  • 107 + 160751 = 160858
  • 149 + 160709 = 160858
  • 239 + 160619 = 160858
  • 317 + 160541 = 160858

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 160,858 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 160858 first appears in π at position 295,549 of the decimal expansion (the 295,549ordinal-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.
