Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181462, here are decompositions:

  • 3 + 181459 = 181462
  • 5 + 181457 = 181462
  • 23 + 181439 = 181462
  • 41 + 181421 = 181462
  • 53 + 181409 = 181462
  • 101 + 181361 = 181462
  • 179 + 181283 = 181462
  • 251 + 181211 = 181462

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 181,462 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 181462 first appears in π at position 701,197 of the decimal expansion (the 701,197ordinal-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.
