Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661318, here are decompositions:

7 + 8661311 = 8661318
37 + 8661281 = 8661318
67 + 8661251 = 8661318
79 + 8661239 = 8661318
101 + 8661217 = 8661318
137 + 8661181 = 8661318
157 + 8661161 = 8661318
181 + 8661137 = 8661318

Showing the first eight; more decompositions exist.
