Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622820, here are decompositions:

  • 11 + 31622809 = 31622820
  • 17 + 31622803 = 31622820
  • 41 + 31622779 = 31622820
  • 43 + 31622777 = 31622820
  • 79 + 31622741 = 31622820
  • 107 + 31622713 = 31622820
  • 127 + 31622693 = 31622820
  • 137 + 31622683 = 31622820

Showing the first eight; more decompositions exist.
