Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624390, here are decompositions:

13 + 33624377 = 33624390
17 + 33624373 = 33624390
47 + 33624343 = 33624390
83 + 33624307 = 33624390
157 + 33624233 = 33624390
181 + 33624209 = 33624390
199 + 33624191 = 33624390
257 + 33624133 = 33624390

Showing the first eight; more decompositions exist.
