Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515490, here are decompositions:

17 + 33515473 = 33515490
53 + 33515437 = 33515490
59 + 33515431 = 33515490
131 + 33515359 = 33515490
149 + 33515341 = 33515490
157 + 33515333 = 33515490
167 + 33515323 = 33515490
191 + 33515299 = 33515490

Showing the first eight; more decompositions exist.
