Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538044, here are decompositions:

  • 11 + 31538033 = 31538044
  • 47 + 31537997 = 31538044
  • 173 + 31537871 = 31538044
  • 353 + 31537691 = 31538044
  • 563 + 31537481 = 31538044
  • 653 + 31537391 = 31538044
  • 773 + 31537271 = 31538044
  • 821 + 31537223 = 31538044

Showing the first eight; more decompositions exist.
