Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661472, here are decompositions:

3 + 8661469 = 8661472
11 + 8661461 = 8661472
59 + 8661413 = 8661472
89 + 8661383 = 8661472
191 + 8661281 = 8661472
233 + 8661239 = 8661472
269 + 8661203 = 8661472
311 + 8661161 = 8661472

Showing the first eight; more decompositions exist.
