Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524896, here are decompositions:

  • 3 + 31524893 = 31524896
  • 103 + 31524793 = 31524896
  • 223 + 31524673 = 31524896
  • 373 + 31524523 = 31524896
  • 379 + 31524517 = 31524896
  • 397 + 31524499 = 31524896
  • 619 + 31524277 = 31524896
  • 673 + 31524223 = 31524896

Showing the first eight; more decompositions exist.
