Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556680, here are decompositions:

7 + 33556673 = 33556680
67 + 33556613 = 33556680
83 + 33556597 = 33556680
109 + 33556571 = 33556680
149 + 33556531 = 33556680
151 + 33556529 = 33556680
173 + 33556507 = 33556680
181 + 33556499 = 33556680

Showing the first eight; more decompositions exist.
