Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172300, here are decompositions:

  • 3 + 172297 = 172300
  • 17 + 172283 = 172300
  • 41 + 172259 = 172300
  • 83 + 172217 = 172300
  • 101 + 172199 = 172300
  • 131 + 172169 = 172300
  • 173 + 172127 = 172300
  • 251 + 172049 = 172300

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 172,300 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 172300 first appears in π at position 498,602 of the decimal expansion (the 498,602ordinal-suffix:nd 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.
