Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700160, here are decompositions:

47 + 8700113 = 8700160
89 + 8700071 = 8700160
101 + 8700059 = 8700160
113 + 8700047 = 8700160
149 + 8700011 = 8700160
167 + 8699993 = 8700160
179 + 8699981 = 8700160
191 + 8699969 = 8700160

Showing the first eight; more decompositions exist.
