Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82580, here are decompositions:

  • 13 + 82567 = 82580
  • 19 + 82561 = 82580
  • 31 + 82549 = 82580
  • 73 + 82507 = 82580
  • 97 + 82483 = 82580
  • 109 + 82471 = 82580
  • 193 + 82387 = 82580
  • 229 + 82351 = 82580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82580 first appears in π at position 98,959 of the decimal expansion (the 98,959ordinal-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.
