Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624790, here are decompositions:

17 + 8624773 = 8624790
19 + 8624771 = 8624790
37 + 8624753 = 8624790
73 + 8624717 = 8624790
113 + 8624677 = 8624790
157 + 8624633 = 8624790
173 + 8624617 = 8624790
191 + 8624599 = 8624790

Showing the first eight; more decompositions exist.
