Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661396, here are decompositions:

13 + 8661383 = 8661396
43 + 8661353 = 8661396
157 + 8661239 = 8661396
173 + 8661223 = 8661396
179 + 8661217 = 8661396
193 + 8661203 = 8661396
199 + 8661197 = 8661396
223 + 8661173 = 8661396

Showing the first eight; more decompositions exist.
