Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519780, here are decompositions:

11 + 33519769 = 33519780
29 + 33519751 = 33519780
31 + 33519749 = 33519780
53 + 33519727 = 33519780
71 + 33519709 = 33519780
137 + 33519643 = 33519780
157 + 33519623 = 33519780
163 + 33519617 = 33519780

Showing the first eight; more decompositions exist.
