Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600778, here are decompositions:

31 + 8600747 = 8600778
37 + 8600741 = 8600778
59 + 8600719 = 8600778
61 + 8600717 = 8600778
101 + 8600677 = 8600778
139 + 8600639 = 8600778
149 + 8600629 = 8600778
157 + 8600621 = 8600778

Showing the first eight; more decompositions exist.
