Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168358, here are decompositions:

  • 5 + 168353 = 168358
  • 11 + 168347 = 168358
  • 89 + 168269 = 168358
  • 131 + 168227 = 168358
  • 269 + 168089 = 168358
  • 467 + 167891 = 168358
  • 479 + 167879 = 168358
  • 557 + 167801 = 168358

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 168,358 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 168358 first appears in π at position 201,305 of the decimal expansion (the 201,305ordinal-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.
