Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622048, here are decompositions:

  • 67 + 31621981 = 31622048
  • 151 + 31621897 = 31622048
  • 379 + 31621669 = 31622048
  • 397 + 31621651 = 31622048
  • 457 + 31621591 = 31622048
  • 487 + 31621561 = 31622048
  • 541 + 31621507 = 31622048
  • 547 + 31621501 = 31622048

Showing the first eight; more decompositions exist.
