Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135208, here are decompositions:

  • 11 + 135197 = 135208
  • 89 + 135119 = 135208
  • 107 + 135101 = 135208
  • 131 + 135077 = 135208
  • 149 + 135059 = 135208
  • 179 + 135029 = 135208
  • 191 + 135017 = 135208
  • 257 + 134951 = 135208

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 135,208 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 135208 first appears in π at position 277,948 of the decimal expansion (the 277,948ordinal-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.
