Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626388, here are decompositions:

67 + 33626321 = 33626388
79 + 33626309 = 33626388
101 + 33626287 = 33626388
139 + 33626249 = 33626388
151 + 33626237 = 33626388
157 + 33626231 = 33626388
277 + 33626111 = 33626388
281 + 33626107 = 33626388

Showing the first eight; more decompositions exist.
