Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617170, here are decompositions:

17 + 8617153 = 8617170
41 + 8617129 = 8617170
61 + 8617109 = 8617170
73 + 8617097 = 8617170
97 + 8617073 = 8617170
173 + 8616997 = 8617170
179 + 8616991 = 8617170
181 + 8616989 = 8617170

Showing the first eight; more decompositions exist.
