Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702128, here are decompositions:

131 + 8701997 = 8702128
137 + 8701991 = 8702128
167 + 8701961 = 8702128
179 + 8701949 = 8702128
251 + 8701877 = 8702128
257 + 8701871 = 8702128
317 + 8701811 = 8702128
419 + 8701709 = 8702128

Showing the first eight; more decompositions exist.
