Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620994, here are decompositions:

43 + 8620951 = 8620994
97 + 8620897 = 8620994
271 + 8620723 = 8620994
307 + 8620687 = 8620994
331 + 8620663 = 8620994
373 + 8620621 = 8620994
601 + 8620393 = 8620994
727 + 8620267 = 8620994

Showing the first eight; more decompositions exist.
