Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543664, here are decompositions:

3 + 33543661 = 33543664
23 + 33543641 = 33543664
491 + 33543173 = 33543664
503 + 33543161 = 33543664
593 + 33543071 = 33543664
647 + 33543017 = 33543664
677 + 33542987 = 33543664
683 + 33542981 = 33543664

Showing the first eight; more decompositions exist.
