Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543682, here are decompositions:

  • 13 + 31543669 = 31543682
  • 103 + 31543579 = 31543682
  • 139 + 31543543 = 31543682
  • 151 + 31543531 = 31543682
  • 193 + 31543489 = 31543682
  • 229 + 31543453 = 31543682
  • 409 + 31543273 = 31543682
  • 439 + 31543243 = 31543682

Showing the first eight; more decompositions exist.
