Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57808, here are decompositions:

  • 5 + 57803 = 57808
  • 17 + 57791 = 57808
  • 71 + 57737 = 57808
  • 89 + 57719 = 57808
  • 167 + 57641 = 57808
  • 251 + 57557 = 57808
  • 281 + 57527 = 57808
  • 419 + 57389 = 57808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 57808 first appears in π at position 205,669 of the decimal expansion (the 205,669ordinal-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.
