Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670120, here are decompositions:

13 + 8670107 = 8670120
31 + 8670089 = 8670120
79 + 8670041 = 8670120
83 + 8670037 = 8670120
89 + 8670031 = 8670120
113 + 8670007 = 8670120
127 + 8669993 = 8670120
131 + 8669989 = 8670120

Showing the first eight; more decompositions exist.
