Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9826, here are decompositions:

  • 23 + 9803 = 9826
  • 59 + 9767 = 9826
  • 83 + 9743 = 9826
  • 107 + 9719 = 9826
  • 137 + 9689 = 9826
  • 149 + 9677 = 9826
  • 197 + 9629 = 9826
  • 239 + 9587 = 9826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9826 first appears in π at position 13,271 of the decimal expansion (the 13,271ordinal-suffix:st 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.
