Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188802, here are decompositions:

  • 11 + 188791 = 188802
  • 23 + 188779 = 188802
  • 73 + 188729 = 188802
  • 83 + 188719 = 188802
  • 101 + 188701 = 188802
  • 109 + 188693 = 188802
  • 149 + 188653 = 188802
  • 181 + 188621 = 188802

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 188,802 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 188802 first appears in π at position 509,085 of the decimal expansion (the 509,085ordinal-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.
