Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624844, here are decompositions:

23 + 8624821 = 8624844
37 + 8624807 = 8624844
71 + 8624773 = 8624844
73 + 8624771 = 8624844
127 + 8624717 = 8624844
131 + 8624713 = 8624844
167 + 8624677 = 8624844
211 + 8624633 = 8624844

Showing the first eight; more decompositions exist.
