Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556750, here are decompositions:

  • 3 + 31556747 = 31556750
  • 13 + 31556737 = 31556750
  • 97 + 31556653 = 31556750
  • 103 + 31556647 = 31556750
  • 193 + 31556557 = 31556750
  • 271 + 31556479 = 31556750
  • 283 + 31556467 = 31556750
  • 397 + 31556353 = 31556750

Showing the first eight; more decompositions exist.
