Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701650, here are decompositions:

7 + 8701643 = 8701650
19 + 8701631 = 8701650
29 + 8701621 = 8701650
73 + 8701577 = 8701650
79 + 8701571 = 8701650
131 + 8701519 = 8701650
151 + 8701499 = 8701650
157 + 8701493 = 8701650

Showing the first eight; more decompositions exist.
