Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444948, here are decompositions:

  • 11 + 31444937 = 31444948
  • 47 + 31444901 = 31444948
  • 71 + 31444877 = 31444948
  • 257 + 31444691 = 31444948
  • 317 + 31444631 = 31444948
  • 389 + 31444559 = 31444948
  • 401 + 31444547 = 31444948
  • 569 + 31444379 = 31444948

Showing the first eight; more decompositions exist.
