Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624646, here are decompositions:

13 + 8624633 = 8624646
29 + 8624617 = 8624646
47 + 8624599 = 8624646
73 + 8624573 = 8624646
139 + 8624507 = 8624646
197 + 8624449 = 8624646
263 + 8624383 = 8624646
293 + 8624353 = 8624646

Showing the first eight; more decompositions exist.
