Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503728, here are decompositions:

17 + 33503711 = 33503728
101 + 33503627 = 33503728
317 + 33503411 = 33503728
359 + 33503369 = 33503728
449 + 33503279 = 33503728
641 + 33503087 = 33503728
647 + 33503081 = 33503728
659 + 33503069 = 33503728

Showing the first eight; more decompositions exist.
