Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174872, here are decompositions:

  • 13 + 174859 = 174872
  • 43 + 174829 = 174872
  • 73 + 174799 = 174872
  • 109 + 174763 = 174872
  • 151 + 174721 = 174872
  • 193 + 174679 = 174872
  • 199 + 174673 = 174872
  • 223 + 174649 = 174872

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 174,872 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 174872 first appears in π at position 7,129 of the decimal expansion (the 7,129ordinal-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.
