Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578568, here are decompositions:

11 + 33578557 = 33578568
59 + 33578509 = 33578568
61 + 33578507 = 33578568
71 + 33578497 = 33578568
131 + 33578437 = 33578568
139 + 33578429 = 33578568
157 + 33578411 = 33578568
181 + 33578387 = 33578568

Showing the first eight; more decompositions exist.
