Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172292, here are decompositions:

  • 13 + 172279 = 172292
  • 73 + 172219 = 172292
  • 79 + 172213 = 172292
  • 139 + 172153 = 172292
  • 199 + 172093 = 172292
  • 223 + 172069 = 172292
  • 271 + 172021 = 172292
  • 283 + 172009 = 172292

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 172,292 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 172292 first appears in π at position 183,714 of the decimal expansion (the 183,714ordinal-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.
