Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661162, here are decompositions:

43 + 8661119 = 8661162
73 + 8661089 = 8661162
101 + 8661061 = 8661162
113 + 8661049 = 8661162
179 + 8660983 = 8661162
193 + 8660969 = 8661162
229 + 8660933 = 8661162
233 + 8660929 = 8661162

Showing the first eight; more decompositions exist.
