Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519980, here are decompositions:

31 + 33519949 = 33519980
37 + 33519943 = 33519980
73 + 33519907 = 33519980
103 + 33519877 = 33519980
211 + 33519769 = 33519980
229 + 33519751 = 33519980
271 + 33519709 = 33519980
337 + 33519643 = 33519980

Showing the first eight; more decompositions exist.
