Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164432, here are decompositions:

  • 3 + 164429 = 164432
  • 13 + 164419 = 164432
  • 19 + 164413 = 164432
  • 61 + 164371 = 164432
  • 181 + 164251 = 164432
  • 193 + 164239 = 164432
  • 199 + 164233 = 164432
  • 223 + 164209 = 164432

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 164,432 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 164432 first appears in π at position 528,889 of the decimal expansion (the 528,889ordinal-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.
