Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103580, here are decompositions:

  • 3 + 103577 = 103580
  • 7 + 103573 = 103580
  • 13 + 103567 = 103580
  • 19 + 103561 = 103580
  • 31 + 103549 = 103580
  • 97 + 103483 = 103580
  • 109 + 103471 = 103580
  • 157 + 103423 = 103580

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 103,580 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 103580 first appears in π at position 97,805 of the decimal expansion (the 97,805ordinal-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.
