Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484816, here are decompositions:

  • 19 + 31484797 = 31484816
  • 199 + 31484617 = 31484816
  • 283 + 31484533 = 31484816
  • 313 + 31484503 = 31484816
  • 367 + 31484449 = 31484816
  • 439 + 31484377 = 31484816
  • 457 + 31484359 = 31484816
  • 463 + 31484353 = 31484816

Showing the first eight; more decompositions exist.
