Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515778, here are decompositions:

5 + 33515773 = 33515778
7 + 33515771 = 33515778
19 + 33515759 = 33515778
59 + 33515719 = 33515778
67 + 33515711 = 33515778
71 + 33515707 = 33515778
199 + 33515579 = 33515778
211 + 33515567 = 33515778

Showing the first eight; more decompositions exist.
