Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624840, here are decompositions:

23 + 33624817 = 33624840
37 + 33624803 = 33624840
71 + 33624769 = 33624840
97 + 33624743 = 33624840
107 + 33624733 = 33624840
157 + 33624683 = 33624840
199 + 33624641 = 33624840
211 + 33624629 = 33624840

Showing the first eight; more decompositions exist.
