Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617120, here are decompositions:

11 + 8617109 = 8617120
23 + 8617097 = 8617120
47 + 8617073 = 8617120
131 + 8616989 = 8617120
173 + 8616947 = 8617120
233 + 8616887 = 8617120
251 + 8616869 = 8617120
293 + 8616827 = 8617120

Showing the first eight; more decompositions exist.
