Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670072, here are decompositions:

31 + 8670041 = 8670072
41 + 8670031 = 8670072
43 + 8670029 = 8670072
79 + 8669993 = 8670072
83 + 8669989 = 8670072
109 + 8669963 = 8670072
149 + 8669923 = 8670072
179 + 8669893 = 8670072

Showing the first eight; more decompositions exist.
