Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624642, here are decompositions:

13 + 33624629 = 33624642
31 + 33624611 = 33624642
59 + 33624583 = 33624642
71 + 33624571 = 33624642
101 + 33624541 = 33624642
131 + 33624511 = 33624642
199 + 33624443 = 33624642
211 + 33624431 = 33624642

Showing the first eight; more decompositions exist.
