Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82500, here are decompositions:

  • 7 + 82493 = 82500
  • 13 + 82487 = 82500
  • 17 + 82483 = 82500
  • 29 + 82471 = 82500
  • 31 + 82469 = 82500
  • 37 + 82463 = 82500
  • 43 + 82457 = 82500
  • 79 + 82421 = 82500

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82500 first appears in π at position 17,077 of the decimal expansion (the 17,077ordinal-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.
