Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550, here are decompositions:

  • 3 + 31547 = 31550
  • 7 + 31543 = 31550
  • 19 + 31531 = 31550
  • 37 + 31513 = 31550
  • 61 + 31489 = 31550
  • 73 + 31477 = 31550
  • 157 + 31393 = 31550
  • 163 + 31387 = 31550

Showing the first eight; more decompositions exist.
