Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515442, here are decompositions:

5 + 33515437 = 33515442
11 + 33515431 = 33515442
73 + 33515369 = 33515442
83 + 33515359 = 33515442
101 + 33515341 = 33515442
109 + 33515333 = 33515442
199 + 33515243 = 33515442
211 + 33515231 = 33515442

Showing the first eight; more decompositions exist.
