Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656356, here are decompositions:

17 + 8656339 = 8656356
43 + 8656313 = 8656356
73 + 8656283 = 8656356
83 + 8656273 = 8656356
103 + 8656253 = 8656356
167 + 8656189 = 8656356
179 + 8656177 = 8656356
193 + 8656163 = 8656356

Showing the first eight; more decompositions exist.
