Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180358, here are decompositions:

  • 11 + 180347 = 180358
  • 41 + 180317 = 180358
  • 47 + 180311 = 180358
  • 71 + 180287 = 180358
  • 137 + 180221 = 180358
  • 179 + 180179 = 180358
  • 197 + 180161 = 180358
  • 281 + 180077 = 180358

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 180,358 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 180358 first appears in π at position 23,331 of the decimal expansion (the 23,331ordinal-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.
