Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624910, here are decompositions:

  • 3 + 31624907 = 31624910
  • 61 + 31624849 = 31624910
  • 73 + 31624837 = 31624910
  • 103 + 31624807 = 31624910
  • 127 + 31624783 = 31624910
  • 157 + 31624753 = 31624910
  • 193 + 31624717 = 31624910
  • 211 + 31624699 = 31624910

Showing the first eight; more decompositions exist.
