Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538018, here are decompositions:

5 + 33538013 = 33538018
47 + 33537971 = 33538018
179 + 33537839 = 33538018
251 + 33537767 = 33538018
317 + 33537701 = 33538018
419 + 33537599 = 33538018
461 + 33537557 = 33538018
467 + 33537551 = 33538018

Showing the first eight; more decompositions exist.
