Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172610, here are decompositions:

  • 3 + 172607 = 172610
  • 7 + 172603 = 172610
  • 13 + 172597 = 172610
  • 37 + 172573 = 172610
  • 103 + 172507 = 172610
  • 199 + 172411 = 172610
  • 211 + 172399 = 172610
  • 313 + 172297 = 172610

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 172,610 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 172610 first appears in π at position 899,860 of the decimal expansion (the 899,860ordinal-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.
