Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515772, here are decompositions:

13 + 33515759 = 33515772
53 + 33515719 = 33515772
61 + 33515711 = 33515772
71 + 33515701 = 33515772
79 + 33515693 = 33515772
139 + 33515633 = 33515772
163 + 33515609 = 33515772
179 + 33515593 = 33515772

Showing the first eight; more decompositions exist.
