Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625066, here are decompositions:

  • 7 + 31625059 = 31625066
  • 127 + 31624939 = 31625066
  • 139 + 31624927 = 31625066
  • 229 + 31624837 = 31625066
  • 283 + 31624783 = 31625066
  • 313 + 31624753 = 31625066
  • 349 + 31624717 = 31625066
  • 367 + 31624699 = 31625066

Showing the first eight; more decompositions exist.
