Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700138, here are decompositions:

17 + 8700121 = 8700138
59 + 8700079 = 8700138
67 + 8700071 = 8700138
79 + 8700059 = 8700138
101 + 8700037 = 8700138
107 + 8700031 = 8700138
127 + 8700011 = 8700138
131 + 8700007 = 8700138

Showing the first eight; more decompositions exist.
