Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487938, here are decompositions:

31 + 33487907 = 33487938
37 + 33487901 = 33487938
61 + 33487877 = 33487938
79 + 33487859 = 33487938
167 + 33487771 = 33487938
179 + 33487759 = 33487938
181 + 33487757 = 33487938
257 + 33487681 = 33487938

Showing the first eight; more decompositions exist.
