Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529784, here are decompositions:

  • 67 + 31529717 = 31529784
  • 103 + 31529681 = 31529784
  • 107 + 31529677 = 31529784
  • 113 + 31529671 = 31529784
  • 191 + 31529593 = 31529784
  • 227 + 31529557 = 31529784
  • 233 + 31529551 = 31529784
  • 263 + 31529521 = 31529784

Showing the first eight; more decompositions exist.
