Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130202, here are decompositions:

  • 3 + 130199 = 130202
  • 19 + 130183 = 130202
  • 31 + 130171 = 130202
  • 103 + 130099 = 130202
  • 151 + 130051 = 130202
  • 181 + 130021 = 130202
  • 199 + 130003 = 130202
  • 283 + 129919 = 130202

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 130,202 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 130202 first appears in π at position 990,768 of the decimal expansion (the 990,768ordinal-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.
