Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670144, here are decompositions:

17 + 8670127 = 8670144
37 + 8670107 = 8670144
73 + 8670071 = 8670144
103 + 8670041 = 8670144
107 + 8670037 = 8670144
113 + 8670031 = 8670144
137 + 8670007 = 8670144
151 + 8669993 = 8670144

Showing the first eight; more decompositions exist.
