Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82660, here are decompositions:

  • 3 + 82657 = 82660
  • 41 + 82619 = 82660
  • 47 + 82613 = 82660
  • 59 + 82601 = 82660
  • 89 + 82571 = 82660
  • 101 + 82559 = 82660
  • 131 + 82529 = 82660
  • 167 + 82493 = 82660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82660 first appears in π at position 134,124 of the decimal expansion (the 134,124ordinal-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.
