Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62720, here are decompositions:

  • 19 + 62701 = 62720
  • 37 + 62683 = 62720
  • 61 + 62659 = 62720
  • 67 + 62653 = 62720
  • 103 + 62617 = 62720
  • 139 + 62581 = 62720
  • 157 + 62563 = 62720
  • 181 + 62539 = 62720

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 62720 first appears in π at position 5,224 of the decimal expansion (the 5,224ordinal-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.
