Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705646, here are decompositions:

7 + 8705639 = 8705646
29 + 8705617 = 8705646
73 + 8705573 = 8705646
97 + 8705549 = 8705646
127 + 8705519 = 8705646
139 + 8705507 = 8705646
163 + 8705483 = 8705646
179 + 8705467 = 8705646

Showing the first eight; more decompositions exist.
