Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705620, here are decompositions:

3 + 8705617 = 8705620
47 + 8705573 = 8705620
59 + 8705561 = 8705620
71 + 8705549 = 8705620
89 + 8705531 = 8705620
101 + 8705519 = 8705620
113 + 8705507 = 8705620
137 + 8705483 = 8705620

Showing the first eight; more decompositions exist.
