Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708628, here are decompositions:

7 + 8708621 = 8708628
11 + 8708617 = 8708628
17 + 8708611 = 8708628
37 + 8708591 = 8708628
101 + 8708527 = 8708628
107 + 8708521 = 8708628
109 + 8708519 = 8708628
127 + 8708501 = 8708628

Showing the first eight; more decompositions exist.
