Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700148, here are decompositions:

89 + 8700059 = 8700148
101 + 8700047 = 8700148
137 + 8700011 = 8700148
167 + 8699981 = 8700148
179 + 8699969 = 8700148
269 + 8699879 = 8700148
647 + 8699501 = 8700148
659 + 8699489 = 8700148

Showing the first eight; more decompositions exist.
