Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617156, here are decompositions:

3 + 8617153 = 8617156
47 + 8617109 = 8617156
59 + 8617097 = 8617156
83 + 8617073 = 8617156
167 + 8616989 = 8617156
239 + 8616917 = 8617156
269 + 8616887 = 8617156
347 + 8616809 = 8617156

Showing the first eight; more decompositions exist.
