Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3828, here are decompositions:

  • 5 + 3823 = 3828
  • 7 + 3821 = 3828
  • 31 + 3797 = 3828
  • 59 + 3769 = 3828
  • 61 + 3767 = 3828
  • 67 + 3761 = 3828
  • 89 + 3739 = 3828
  • 101 + 3727 = 3828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3828 first appears in π at position 5,082 of the decimal expansion (the 5,082ordinal-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.
