Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65824, here are decompositions:

  • 47 + 65777 = 65824
  • 107 + 65717 = 65824
  • 137 + 65687 = 65824
  • 167 + 65657 = 65824
  • 173 + 65651 = 65824
  • 191 + 65633 = 65824
  • 281 + 65543 = 65824
  • 401 + 65423 = 65824

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65824 first appears in π at position 79,567 of the decimal expansion (the 79,567ordinal-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.
