Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27822, here are decompositions:

  • 5 + 27817 = 27822
  • 13 + 27809 = 27822
  • 19 + 27803 = 27822
  • 23 + 27799 = 27822
  • 29 + 27793 = 27822
  • 31 + 27791 = 27822
  • 43 + 27779 = 27822
  • 59 + 27763 = 27822

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27822 first appears in π at position 373,149 of the decimal expansion (the 373,149ordinal-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.
