Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23800, here are decompositions:

  • 11 + 23789 = 23800
  • 47 + 23753 = 23800
  • 53 + 23747 = 23800
  • 59 + 23741 = 23800
  • 113 + 23687 = 23800
  • 131 + 23669 = 23800
  • 137 + 23663 = 23800
  • 167 + 23633 = 23800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23800 first appears in π at position 327,268 of the decimal expansion (the 327,268ordinal-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.
