Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629778, here are decompositions:

7 + 8629771 = 8629778
67 + 8629711 = 8629778
97 + 8629681 = 8629778
127 + 8629651 = 8629778
181 + 8629597 = 8629778
271 + 8629507 = 8629778
331 + 8629447 = 8629778
337 + 8629441 = 8629778

Showing the first eight; more decompositions exist.
