Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718980, here are decompositions:

7 + 8718973 = 8718980
31 + 8718949 = 8718980
73 + 8718907 = 8718980
103 + 8718877 = 8718980
157 + 8718823 = 8718980
181 + 8718799 = 8718980
223 + 8718757 = 8718980
271 + 8718709 = 8718980

Showing the first eight; more decompositions exist.
