Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165852, here are decompositions:

  • 19 + 165833 = 165852
  • 23 + 165829 = 165852
  • 41 + 165811 = 165852
  • 53 + 165799 = 165852
  • 73 + 165779 = 165852
  • 103 + 165749 = 165852
  • 131 + 165721 = 165852
  • 139 + 165713 = 165852

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 165,852 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 165852 first appears in π at position 619,084 of the decimal expansion (the 619,084ordinal-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.
