Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686470, here are decompositions:

7 + 8686463 = 8686470
11 + 8686459 = 8686470
61 + 8686409 = 8686470
73 + 8686397 = 8686470
97 + 8686373 = 8686470
101 + 8686369 = 8686470
109 + 8686361 = 8686470
157 + 8686313 = 8686470

Showing the first eight; more decompositions exist.
