Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702646, here are decompositions:

53 + 8702593 = 8702646
59 + 8702587 = 8702646
89 + 8702557 = 8702646
103 + 8702543 = 8702646
107 + 8702539 = 8702646
149 + 8702497 = 8702646
157 + 8702489 = 8702646
163 + 8702483 = 8702646

Showing the first eight; more decompositions exist.
