Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710778, here are decompositions:

7 + 8710771 = 8710778
31 + 8710747 = 8710778
61 + 8710717 = 8710778
79 + 8710699 = 8710778
151 + 8710627 = 8710778
157 + 8710621 = 8710778
211 + 8710567 = 8710778
337 + 8710441 = 8710778

Showing the first eight; more decompositions exist.
