Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609778, here are decompositions:

5 + 8609773 = 8609778
59 + 8609719 = 8609778
101 + 8609677 = 8609778
109 + 8609669 = 8609778
127 + 8609651 = 8609778
131 + 8609647 = 8609778
139 + 8609639 = 8609778
157 + 8609621 = 8609778

Showing the first eight; more decompositions exist.
