Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637960, here are decompositions:

7 + 8637953 = 8637960
17 + 8637943 = 8637960
31 + 8637929 = 8637960
113 + 8637847 = 8637960
131 + 8637829 = 8637960
139 + 8637821 = 8637960
173 + 8637787 = 8637960
181 + 8637779 = 8637960

Showing the first eight; more decompositions exist.
