Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6838, here are decompositions:

  • 5 + 6833 = 6838
  • 11 + 6827 = 6838
  • 47 + 6791 = 6838
  • 59 + 6779 = 6838
  • 101 + 6737 = 6838
  • 137 + 6701 = 6838
  • 149 + 6689 = 6838
  • 179 + 6659 = 6838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6838 first appears in π at position 2,203 of the decimal expansion (the 2,203ordinal-suffix:rd 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.
