Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670146, here are decompositions:

19 + 8670127 = 8670146
109 + 8670037 = 8670146
139 + 8670007 = 8670146
157 + 8669989 = 8670146
223 + 8669923 = 8670146
379 + 8669767 = 8670146
523 + 8669623 = 8670146
619 + 8669527 = 8670146

Showing the first eight; more decompositions exist.
