Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130206, here are decompositions:

  • 5 + 130201 = 130206
  • 7 + 130199 = 130206
  • 23 + 130183 = 130206
  • 59 + 130147 = 130206
  • 79 + 130127 = 130206
  • 107 + 130099 = 130206
  • 127 + 130079 = 130206
  • 137 + 130069 = 130206

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 130,206 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 130206 first appears in π at position 991,328 of the decimal expansion (the 991,328ordinal-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.
