Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556388, here are decompositions:

7 + 33556381 = 33556388
31 + 33556357 = 33556388
157 + 33556231 = 33556388
181 + 33556207 = 33556388
199 + 33556189 = 33556388
277 + 33556111 = 33556388
337 + 33556051 = 33556388
379 + 33556009 = 33556388

Showing the first eight; more decompositions exist.
