Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617168, here are decompositions:

59 + 8617109 = 8617168
71 + 8617097 = 8617168
167 + 8617001 = 8617168
179 + 8616989 = 8617168
251 + 8616917 = 8617168
257 + 8616911 = 8617168
281 + 8616887 = 8617168
347 + 8616821 = 8617168

Showing the first eight; more decompositions exist.
