Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630778, here are decompositions:

7 + 8630771 = 8630778
19 + 8630759 = 8630778
29 + 8630749 = 8630778
41 + 8630737 = 8630778
109 + 8630669 = 8630778
131 + 8630647 = 8630778
137 + 8630641 = 8630778
139 + 8630639 = 8630778

Showing the first eight; more decompositions exist.
