Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65568, here are decompositions:

  • 5 + 65563 = 65568
  • 11 + 65557 = 65568
  • 17 + 65551 = 65568
  • 29 + 65539 = 65568
  • 31 + 65537 = 65568
  • 47 + 65521 = 65568
  • 71 + 65497 = 65568
  • 89 + 65479 = 65568

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65568 first appears in π at position 42,768 of the decimal expansion (the 42,768ordinal-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.
