Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658356, here are decompositions:

43 + 8658313 = 8658356
67 + 8658289 = 8658356
79 + 8658277 = 8658356
139 + 8658217 = 8658356
163 + 8658193 = 8658356
313 + 8658043 = 8658356
373 + 8657983 = 8658356
433 + 8657923 = 8658356

Showing the first eight; more decompositions exist.
