Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182980, here are decompositions:

  • 11 + 182969 = 182980
  • 23 + 182957 = 182980
  • 47 + 182933 = 182980
  • 53 + 182927 = 182980
  • 59 + 182921 = 182980
  • 113 + 182867 = 182980
  • 167 + 182813 = 182980
  • 191 + 182789 = 182980

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 182,980 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 182980 first appears in π at position 215,521 of the decimal expansion (the 215,521ordinal-suffix:st 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.
