Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736138, here are decompositions:

11 + 8736127 = 8736138
29 + 8736109 = 8736138
41 + 8736097 = 8736138
79 + 8736059 = 8736138
97 + 8736041 = 8736138
101 + 8736037 = 8736138
137 + 8736001 = 8736138
167 + 8735971 = 8736138

Showing the first eight; more decompositions exist.
