Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535850, here are decompositions:

  • 19 + 31535831 = 31535850
  • 23 + 31535827 = 31535850
  • 29 + 31535821 = 31535850
  • 41 + 31535809 = 31535850
  • 53 + 31535797 = 31535850
  • 97 + 31535753 = 31535850
  • 103 + 31535747 = 31535850
  • 109 + 31535741 = 31535850

Showing the first eight; more decompositions exist.
