Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508778, here are decompositions:

139 + 33508639 = 33508778
151 + 33508627 = 33508778
229 + 33508549 = 33508778
271 + 33508507 = 33508778
307 + 33508471 = 33508778
439 + 33508339 = 33508778
487 + 33508291 = 33508778
619 + 33508159 = 33508778

Showing the first eight; more decompositions exist.
