Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620946, here are decompositions:

3 + 8620943 = 8620946
73 + 8620873 = 8620946
199 + 8620747 = 8620946
223 + 8620723 = 8620946
283 + 8620663 = 8620946
307 + 8620639 = 8620946
379 + 8620567 = 8620946
577 + 8620369 = 8620946

Showing the first eight; more decompositions exist.
