Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619528, here are decompositions:

  • 7 + 31619521 = 31619528
  • 19 + 31619509 = 31619528
  • 139 + 31619389 = 31619528
  • 271 + 31619257 = 31619528
  • 337 + 31619191 = 31619528
  • 349 + 31619179 = 31619528
  • 487 + 31619041 = 31619528
  • 547 + 31618981 = 31619528

Showing the first eight; more decompositions exist.
