Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478518, here are decompositions:

41 + 33478477 = 33478518
79 + 33478439 = 33478518
97 + 33478421 = 33478518
107 + 33478411 = 33478518
127 + 33478391 = 33478518
131 + 33478387 = 33478518
181 + 33478337 = 33478518
211 + 33478307 = 33478518

Showing the first eight; more decompositions exist.
