Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182972, here are decompositions:

  • 3 + 182969 = 182972
  • 19 + 182953 = 182972
  • 43 + 182929 = 182972
  • 73 + 182899 = 182972
  • 79 + 182893 = 182972
  • 151 + 182821 = 182972
  • 193 + 182779 = 182972
  • 199 + 182773 = 182972

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 182,972 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 182972 first appears in π at position 799,206 of the decimal expansion (the 799,206ordinal-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.
