Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717778, here are decompositions:

5 + 8717773 = 8717778
11 + 8717767 = 8717778
29 + 8717749 = 8717778
31 + 8717747 = 8717778
37 + 8717741 = 8717778
61 + 8717717 = 8717778
89 + 8717689 = 8717778
101 + 8717677 = 8717778

Showing the first eight; more decompositions exist.
