Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172202, here are decompositions:

  • 3 + 172199 = 172202
  • 31 + 172171 = 172202
  • 109 + 172093 = 172202
  • 181 + 172021 = 172202
  • 193 + 172009 = 172202
  • 313 + 171889 = 172202
  • 379 + 171823 = 172202
  • 409 + 171793 = 172202

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 172,202 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 172202 first appears in π at position 181,416 of the decimal expansion (the 181,416ordinal-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.
