Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651658, here are decompositions:

11 + 8651647 = 8651658
19 + 8651639 = 8651658
31 + 8651627 = 8651658
79 + 8651579 = 8651658
109 + 8651549 = 8651658
151 + 8651507 = 8651658
157 + 8651501 = 8651658
199 + 8651459 = 8651658

Showing the first eight; more decompositions exist.
