Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567630, here are decompositions:

  • 11 + 31567619 = 31567630
  • 71 + 31567559 = 31567630
  • 179 + 31567451 = 31567630
  • 233 + 31567397 = 31567630
  • 317 + 31567313 = 31567630
  • 359 + 31567271 = 31567630
  • 389 + 31567241 = 31567630
  • 587 + 31567043 = 31567630

Showing the first eight; more decompositions exist.
