Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548732, here are decompositions:

  • 73 + 31548659 = 31548732
  • 79 + 31548653 = 31548732
  • 113 + 31548619 = 31548732
  • 139 + 31548593 = 31548732
  • 181 + 31548551 = 31548732
  • 199 + 31548533 = 31548732
  • 211 + 31548521 = 31548732
  • 233 + 31548499 = 31548732

Showing the first eight; more decompositions exist.
