Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477940, here are decompositions:

11 + 33477929 = 33477940
59 + 33477881 = 33477940
227 + 33477713 = 33477940
257 + 33477683 = 33477940
281 + 33477659 = 33477940
449 + 33477491 = 33477940
467 + 33477473 = 33477940
593 + 33477347 = 33477940

Showing the first eight; more decompositions exist.
