Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670156, here are decompositions:

29 + 8670127 = 8670156
67 + 8670089 = 8670156
127 + 8670029 = 8670156
149 + 8670007 = 8670156
163 + 8669993 = 8670156
167 + 8669989 = 8670156
193 + 8669963 = 8670156
227 + 8669929 = 8670156

Showing the first eight; more decompositions exist.
