Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535946, here are decompositions:

  • 5 + 31535941 = 31535946
  • 7 + 31535939 = 31535946
  • 37 + 31535909 = 31535946
  • 67 + 31535879 = 31535946
  • 137 + 31535809 = 31535946
  • 149 + 31535797 = 31535946
  • 193 + 31535753 = 31535946
  • 199 + 31535747 = 31535946

Showing the first eight; more decompositions exist.
