Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707138, here are decompositions:

47 + 8707091 = 8707138
101 + 8707037 = 8707138
107 + 8707031 = 8707138
131 + 8707007 = 8707138
191 + 8706947 = 8707138
257 + 8706881 = 8707138
269 + 8706869 = 8707138
347 + 8706791 = 8707138

Showing the first eight; more decompositions exist.
