Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538228, here are decompositions:

5 + 33538223 = 33538228
11 + 33538217 = 33538228
137 + 33538091 = 33538228
179 + 33538049 = 33538228
257 + 33537971 = 33538228
389 + 33537839 = 33538228
419 + 33537809 = 33538228
431 + 33537797 = 33538228

Showing the first eight; more decompositions exist.
