Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185850, here are decompositions:

  • 17 + 185833 = 185850
  • 19 + 185831 = 185850
  • 29 + 185821 = 185850
  • 31 + 185819 = 185850
  • 37 + 185813 = 185850
  • 53 + 185797 = 185850
  • 61 + 185789 = 185850
  • 83 + 185767 = 185850

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 185,850 and was likely granted around 1875.

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

Position in π

The digit sequence 185850 first appears in π at position 105,614 of the decimal expansion (the 105,614ordinal-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.
