Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518146, here are decompositions:

  • 17 + 518129 = 518146
  • 23 + 518123 = 518146
  • 47 + 518099 = 518146
  • 89 + 518057 = 518146
  • 179 + 517967 = 518146
  • 197 + 517949 = 518146
  • 227 + 517919 = 518146
  • 269 + 517877 = 518146

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 518,146 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 518146 first appears in π at position 154,235 of the decimal expansion (the 154,235ordinal-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.
