Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670138, here are decompositions:

11 + 8670127 = 8670138
31 + 8670107 = 8670138
67 + 8670071 = 8670138
97 + 8670041 = 8670138
101 + 8670037 = 8670138
107 + 8670031 = 8670138
109 + 8670029 = 8670138
131 + 8670007 = 8670138

Showing the first eight; more decompositions exist.
