Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601778, here are decompositions:

5 + 8601773 = 8601778
11 + 8601767 = 8601778
71 + 8601707 = 8601778
89 + 8601689 = 8601778
131 + 8601647 = 8601778
137 + 8601641 = 8601778
149 + 8601629 = 8601778
191 + 8601587 = 8601778

Showing the first eight; more decompositions exist.
