Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130280, here are decompositions:

  • 13 + 130267 = 130280
  • 19 + 130261 = 130280
  • 79 + 130201 = 130280
  • 97 + 130183 = 130280
  • 109 + 130171 = 130280
  • 181 + 130099 = 130280
  • 193 + 130087 = 130280
  • 211 + 130069 = 130280

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 130,280 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 130280 first appears in π at position 585,450 of the decimal expansion (the 585,450ordinal-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.
