Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40566, here are decompositions:

  • 7 + 40559 = 40566
  • 23 + 40543 = 40566
  • 37 + 40529 = 40566
  • 47 + 40519 = 40566
  • 59 + 40507 = 40566
  • 67 + 40499 = 40566
  • 73 + 40493 = 40566
  • 79 + 40487 = 40566

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40566 first appears in π at position 22,710 of the decimal expansion (the 22,710ordinal-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.
