Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454536, here are decompositions:

  • 23 + 31454513 = 31454536
  • 53 + 31454483 = 31454536
  • 317 + 31454219 = 31454536
  • 389 + 31454147 = 31454536
  • 419 + 31454117 = 31454536
  • 593 + 31453943 = 31454536
  • 653 + 31453883 = 31454536
  • 809 + 31453727 = 31454536

Showing the first eight; more decompositions exist.
