Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181056, here are decompositions:

  • 17 + 181039 = 181056
  • 37 + 181019 = 181056
  • 53 + 181003 = 181056
  • 97 + 180959 = 181056
  • 107 + 180949 = 181056
  • 149 + 180907 = 181056
  • 173 + 180883 = 181056
  • 257 + 180799 = 181056

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 181,056 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 181056 first appears in π at position 49,014 of the decimal expansion (the 49,014ordinal-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.
