Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42970, here are decompositions:

  • 3 + 42967 = 42970
  • 17 + 42953 = 42970
  • 41 + 42929 = 42970
  • 47 + 42923 = 42970
  • 71 + 42899 = 42970
  • 107 + 42863 = 42970
  • 131 + 42839 = 42970
  • 149 + 42821 = 42970

Showing the first eight; more decompositions exist.
