Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180588, here are decompositions:

  • 19 + 180569 = 180588
  • 41 + 180547 = 180588
  • 47 + 180541 = 180588
  • 97 + 180491 = 180588
  • 151 + 180437 = 180588
  • 197 + 180391 = 180588
  • 227 + 180361 = 180588
  • 241 + 180347 = 180588

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 180,588 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 180588 first appears in π at position 348,515 of the decimal expansion (the 348,515ordinal-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.
