Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661376, here are decompositions:

23 + 8661353 = 8661376
137 + 8661239 = 8661376
173 + 8661203 = 8661376
179 + 8661197 = 8661376
239 + 8661137 = 8661376
257 + 8661119 = 8661376
389 + 8660987 = 8661376
443 + 8660933 = 8661376

Showing the first eight; more decompositions exist.
