Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64988, here are decompositions:

  • 19 + 64969 = 64988
  • 37 + 64951 = 64988
  • 61 + 64927 = 64988
  • 67 + 64921 = 64988
  • 97 + 64891 = 64988
  • 109 + 64879 = 64988
  • 139 + 64849 = 64988
  • 241 + 64747 = 64988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64988 first appears in π at position 56,767 of the decimal expansion (the 56,767ordinal-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.
