Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172322, here are decompositions:

  • 43 + 172279 = 172322
  • 79 + 172243 = 172322
  • 103 + 172219 = 172322
  • 109 + 172213 = 172322
  • 151 + 172171 = 172322
  • 229 + 172093 = 172322
  • 313 + 172009 = 172322
  • 433 + 171889 = 172322

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 172,322 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 172322 first appears in π at position 700,216 of the decimal expansion (the 700,216ordinal-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.
