Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543626, here are decompositions:

  • 47 + 31543579 = 31543626
  • 83 + 31543543 = 31543626
  • 97 + 31543529 = 31543626
  • 137 + 31543489 = 31543626
  • 173 + 31543453 = 31543626
  • 197 + 31543429 = 31543626
  • 229 + 31543397 = 31543626
  • 277 + 31543349 = 31543626

Showing the first eight; more decompositions exist.
