Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165862, here are decompositions:

  • 5 + 165857 = 165862
  • 29 + 165833 = 165862
  • 83 + 165779 = 165862
  • 113 + 165749 = 165862
  • 149 + 165713 = 165862
  • 251 + 165611 = 165862
  • 293 + 165569 = 165862
  • 311 + 165551 = 165862

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 165,862 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 165862 first appears in π at position 80,782 of the decimal expansion (the 80,782ordinal-suffix:nd 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.
