Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538664, here are decompositions:

  • 31 + 33538633 = 33538664
  • 37 + 33538627 = 33538664
  • 157 + 33538507 = 33538664
  • 223 + 33538441 = 33538664
  • 277 + 33538387 = 33538664
  • 337 + 33538327 = 33538664
  • 433 + 33538231 = 33538664
  • 457 + 33538207 = 33538664

Showing the first eight; more decompositions exist.
