Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11970, here are decompositions:

  • 11 + 11959 = 11970
  • 17 + 11953 = 11970
  • 29 + 11941 = 11970
  • 31 + 11939 = 11970
  • 37 + 11933 = 11970
  • 43 + 11927 = 11970
  • 47 + 11923 = 11970
  • 61 + 11909 = 11970

Showing the first eight; more decompositions exist.
