Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705628, here are decompositions:

11 + 8705617 = 8705628
17 + 8705611 = 8705628
67 + 8705561 = 8705628
79 + 8705549 = 8705628
97 + 8705531 = 8705628
101 + 8705527 = 8705628
109 + 8705519 = 8705628
137 + 8705491 = 8705628

Showing the first eight; more decompositions exist.
