Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569508, here are decompositions:

  • 17 + 31569491 = 31569508
  • 29 + 31569479 = 31569508
  • 59 + 31569449 = 31569508
  • 71 + 31569437 = 31569508
  • 149 + 31569359 = 31569508
  • 227 + 31569281 = 31569508
  • 251 + 31569257 = 31569508
  • 401 + 31569107 = 31569508

Showing the first eight; more decompositions exist.
