Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661418, here are decompositions:

5 + 8661413 = 8661418
11 + 8661407 = 8661418
107 + 8661311 = 8661418
137 + 8661281 = 8661418
167 + 8661251 = 8661418
179 + 8661239 = 8661418
257 + 8661161 = 8661418
281 + 8661137 = 8661418

Showing the first eight; more decompositions exist.
