Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165358, here are decompositions:

  • 41 + 165317 = 165358
  • 47 + 165311 = 165358
  • 71 + 165287 = 165358
  • 197 + 165161 = 165358
  • 269 + 165089 = 165358
  • 311 + 165047 = 165358
  • 317 + 165041 = 165358
  • 359 + 164999 = 165358

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 165,358 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 165358 first appears in π at position 336,828 of the decimal expansion (the 336,828ordinal-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.
