Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180590, here are decompositions:

  • 43 + 180547 = 180590
  • 79 + 180511 = 180590
  • 127 + 180463 = 180590
  • 199 + 180391 = 180590
  • 211 + 180379 = 180590
  • 229 + 180361 = 180590
  • 283 + 180307 = 180590
  • 331 + 180259 = 180590

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 180,590 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 180590 first appears in π at position 413,841 of the decimal expansion (the 413,841ordinal-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.
