Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3936, here are decompositions:

  • 5 + 3931 = 3936
  • 7 + 3929 = 3936
  • 13 + 3923 = 3936
  • 17 + 3919 = 3936
  • 19 + 3917 = 3936
  • 29 + 3907 = 3936
  • 47 + 3889 = 3936
  • 59 + 3877 = 3936

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3936 first appears in π at position 283 of the decimal expansion (the 283ordinal-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.
