Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736144, here are decompositions:

5 + 8736139 = 8736144
17 + 8736127 = 8736144
47 + 8736097 = 8736144
71 + 8736073 = 8736144
83 + 8736061 = 8736144
103 + 8736041 = 8736144
107 + 8736037 = 8736144
173 + 8735971 = 8736144

Showing the first eight; more decompositions exist.
