Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3800, here are decompositions:

  • 3 + 3797 = 3800
  • 7 + 3793 = 3800
  • 31 + 3769 = 3800
  • 61 + 3739 = 3800
  • 67 + 3733 = 3800
  • 73 + 3727 = 3800
  • 103 + 3697 = 3800
  • 109 + 3691 = 3800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3800 first appears in π at position 1,596 of the decimal expansion (the 1,596ordinal-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.
