Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624874, here are decompositions:

53 + 8624821 = 8624874
67 + 8624807 = 8624874
101 + 8624773 = 8624874
103 + 8624771 = 8624874
157 + 8624717 = 8624874
197 + 8624677 = 8624874
241 + 8624633 = 8624874
257 + 8624617 = 8624874

Showing the first eight; more decompositions exist.
