Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661356, here are decompositions:

3 + 8661353 = 8661356
103 + 8661253 = 8661356
139 + 8661217 = 8661356
163 + 8661193 = 8661356
307 + 8661049 = 8661356
313 + 8661043 = 8661356
373 + 8660983 = 8661356
409 + 8660947 = 8661356

Showing the first eight; more decompositions exist.
