Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444694, here are decompositions:

  • 3 + 31444691 = 31444694
  • 13 + 31444681 = 31444694
  • 67 + 31444627 = 31444694
  • 103 + 31444591 = 31444694
  • 157 + 31444537 = 31444694
  • 223 + 31444471 = 31444694
  • 241 + 31444453 = 31444694
  • 367 + 31444327 = 31444694

Showing the first eight; more decompositions exist.
