Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135200, here are decompositions:

  • 3 + 135197 = 135200
  • 7 + 135193 = 135200
  • 19 + 135181 = 135200
  • 151 + 135049 = 135200
  • 157 + 135043 = 135200
  • 181 + 135019 = 135200
  • 193 + 135007 = 135200
  • 211 + 134989 = 135200

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 135,200 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 135200 first appears in π at position 706,276 of the decimal expansion (the 706,276ordinal-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.
