Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624640, here are decompositions:

11 + 33624629 = 33624640
29 + 33624611 = 33624640
53 + 33624587 = 33624640
167 + 33624473 = 33624640
197 + 33624443 = 33624640
263 + 33624377 = 33624640
383 + 33624257 = 33624640
431 + 33624209 = 33624640

Showing the first eight; more decompositions exist.
