Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708664, here are decompositions:

7 + 8708657 = 8708664
37 + 8708627 = 8708664
43 + 8708621 = 8708664
47 + 8708617 = 8708664
53 + 8708611 = 8708664
73 + 8708591 = 8708664
127 + 8708537 = 8708664
137 + 8708527 = 8708664

Showing the first eight; more decompositions exist.
