Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661430, here are decompositions:

3 + 8661427 = 8661430
17 + 8661413 = 8661430
23 + 8661407 = 8661430
47 + 8661383 = 8661430
149 + 8661281 = 8661430
179 + 8661251 = 8661430
191 + 8661239 = 8661430
227 + 8661203 = 8661430

Showing the first eight; more decompositions exist.
