Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535986, here are decompositions:

  • 3 + 31535983 = 31535986
  • 5 + 31535981 = 31535986
  • 47 + 31535939 = 31535986
  • 107 + 31535879 = 31535986
  • 233 + 31535753 = 31535986
  • 239 + 31535747 = 31535986
  • 269 + 31535717 = 31535986
  • 347 + 31535639 = 31535986

Showing the first eight; more decompositions exist.
