Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27826, here are decompositions:

  • 3 + 27823 = 27826
  • 17 + 27809 = 27826
  • 23 + 27803 = 27826
  • 47 + 27779 = 27826
  • 53 + 27773 = 27826
  • 59 + 27767 = 27826
  • 83 + 27743 = 27826
  • 89 + 27737 = 27826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27826 first appears in π at position 200,752 of the decimal expansion (the 200,752ordinal-suffix:nd 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.
