Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516016, here are decompositions:

  • 67 + 31515949 = 31516016
  • 79 + 31515937 = 31516016
  • 97 + 31515919 = 31516016
  • 283 + 31515733 = 31516016
  • 313 + 31515703 = 31516016
  • 409 + 31515607 = 31516016
  • 439 + 31515577 = 31516016
  • 457 + 31515559 = 31516016

Showing the first eight; more decompositions exist.
