Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165434, here are decompositions:

  • 37 + 165397 = 165434
  • 43 + 165391 = 165434
  • 67 + 165367 = 165434
  • 103 + 165331 = 165434
  • 223 + 165211 = 165434
  • 331 + 165103 = 165434
  • 397 + 165037 = 165434
  • 433 + 165001 = 165434

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 165,434 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 165434 first appears in π at position 451,043 of the decimal expansion (the 451,043ordinal-suffix:rd 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.
