Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64764, here are decompositions:

  • 17 + 64747 = 64764
  • 47 + 64717 = 64764
  • 71 + 64693 = 64764
  • 97 + 64667 = 64764
  • 101 + 64663 = 64764
  • 103 + 64661 = 64764
  • 131 + 64633 = 64764
  • 137 + 64627 = 64764

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64764 first appears in π at position 229,743 of the decimal expansion (the 229,743ordinal-suffix:rd 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.
