Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172898, here are decompositions:

  • 31 + 172867 = 172898
  • 97 + 172801 = 172898
  • 139 + 172759 = 172898
  • 157 + 172741 = 172898
  • 181 + 172717 = 172898
  • 211 + 172687 = 172898
  • 241 + 172657 = 172898
  • 337 + 172561 = 172898

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 172,898 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 172898 first appears in π at position 21,705 of the decimal expansion (the 21,705ordinal-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.
