Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578646, here are decompositions:

5 + 33578641 = 33578646
29 + 33578617 = 33578646
47 + 33578599 = 33578646
89 + 33578557 = 33578646
113 + 33578533 = 33578646
137 + 33578509 = 33578646
139 + 33578507 = 33578646
149 + 33578497 = 33578646

Showing the first eight; more decompositions exist.
