Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135518, here are decompositions:

  • 7 + 135511 = 135518
  • 109 + 135409 = 135518
  • 127 + 135391 = 135518
  • 151 + 135367 = 135518
  • 199 + 135319 = 135518
  • 241 + 135277 = 135518
  • 277 + 135241 = 135518
  • 307 + 135211 = 135518

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 135,518 and was likely granted around 1872.

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

Position in π

The digit sequence 135518 first appears in π at position 279,162 of the decimal expansion (the 279,162ordinal-suffix:nd 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.
