Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65560, here are decompositions:

  • 3 + 65557 = 65560
  • 17 + 65543 = 65560
  • 23 + 65537 = 65560
  • 41 + 65519 = 65560
  • 113 + 65447 = 65560
  • 137 + 65423 = 65560
  • 167 + 65393 = 65560
  • 179 + 65381 = 65560

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65560 first appears in π at position 55,086 of the decimal expansion (the 55,086ordinal-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.
