Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620980, here are decompositions:

7 + 8620973 = 8620980
29 + 8620951 = 8620980
31 + 8620949 = 8620980
37 + 8620943 = 8620980
83 + 8620897 = 8620980
107 + 8620873 = 8620980
139 + 8620841 = 8620980
223 + 8620757 = 8620980

Showing the first eight; more decompositions exist.
