Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105810, here are decompositions:

  • 41 + 105769 = 105810
  • 43 + 105767 = 105810
  • 59 + 105751 = 105810
  • 83 + 105727 = 105810
  • 109 + 105701 = 105810
  • 127 + 105683 = 105810
  • 137 + 105673 = 105810
  • 157 + 105653 = 105810

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 105,810 and was likely granted around 1870.

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

Position in π

The digit sequence 105810 first appears in π at position 828,481 of the decimal expansion (the 828,481ordinal-suffix:st 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.
