Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180454, here are decompositions:

  • 17 + 180437 = 180454
  • 41 + 180413 = 180454
  • 83 + 180371 = 180454
  • 107 + 180347 = 180454
  • 137 + 180317 = 180454
  • 167 + 180287 = 180454
  • 173 + 180281 = 180454
  • 191 + 180263 = 180454

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 180,454 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 180454 first appears in π at position 580,092 of the decimal expansion (the 580,092ordinal-suffix:nd 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.
