Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620974, here are decompositions:

23 + 8620951 = 8620974
31 + 8620943 = 8620974
101 + 8620873 = 8620974
113 + 8620861 = 8620974
127 + 8620847 = 8620974
227 + 8620747 = 8620974
251 + 8620723 = 8620974
283 + 8620691 = 8620974

Showing the first eight; more decompositions exist.
