Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624940, here are decompositions:

11 + 8624929 = 8624940
19 + 8624921 = 8624940
53 + 8624887 = 8624940
59 + 8624881 = 8624940
67 + 8624873 = 8624940
167 + 8624773 = 8624940
223 + 8624717 = 8624940
227 + 8624713 = 8624940

Showing the first eight; more decompositions exist.
