Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624388, here are decompositions:

11 + 33624377 = 33624388
47 + 33624341 = 33624388
131 + 33624257 = 33624388
179 + 33624209 = 33624388
197 + 33624191 = 33624388
257 + 33624131 = 33624388
311 + 33624077 = 33624388
359 + 33624029 = 33624388

Showing the first eight; more decompositions exist.
