Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557218, here are decompositions:

131 + 33557087 = 33557218
257 + 33556961 = 33557218
281 + 33556937 = 33557218
449 + 33556769 = 33557218
647 + 33556571 = 33557218
659 + 33556559 = 33557218
719 + 33556499 = 33557218
857 + 33556361 = 33557218

Showing the first eight; more decompositions exist.
