Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185560, here are decompositions:

  • 3 + 185557 = 185560
  • 17 + 185543 = 185560
  • 29 + 185531 = 185560
  • 41 + 185519 = 185560
  • 83 + 185477 = 185560
  • 131 + 185429 = 185560
  • 191 + 185369 = 185560
  • 197 + 185363 = 185560

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 185,560 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 185560 first appears in π at position 4,145 of the decimal expansion (the 4,145ordinal-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.
