Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515780, here are decompositions:

7 + 33515773 = 33515780
61 + 33515719 = 33515780
73 + 33515707 = 33515780
79 + 33515701 = 33515780
163 + 33515617 = 33515780
211 + 33515569 = 33515780
241 + 33515539 = 33515780
271 + 33515509 = 33515780

Showing the first eight; more decompositions exist.
