Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447796, here are decompositions:

  • 13 + 31447783 = 31447796
  • 139 + 31447657 = 31447796
  • 223 + 31447573 = 31447796
  • 433 + 31447363 = 31447796
  • 439 + 31447357 = 31447796
  • 463 + 31447333 = 31447796
  • 607 + 31447189 = 31447796
  • 727 + 31447069 = 31447796

Showing the first eight; more decompositions exist.
