Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130580, here are decompositions:

  • 67 + 130513 = 130580
  • 97 + 130483 = 130580
  • 103 + 130477 = 130580
  • 157 + 130423 = 130580
  • 181 + 130399 = 130580
  • 211 + 130369 = 130580
  • 277 + 130303 = 130580
  • 313 + 130267 = 130580

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 130,580 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 130580 first appears in π at position 941,192 of the decimal expansion (the 941,192ordinal-suffix:nd 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.
