Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487340, here are decompositions:

31 + 33487309 = 33487340
67 + 33487273 = 33487340
79 + 33487261 = 33487340
151 + 33487189 = 33487340
193 + 33487147 = 33487340
223 + 33487117 = 33487340
307 + 33487033 = 33487340
499 + 33486841 = 33487340

Showing the first eight; more decompositions exist.
