Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670186, here are decompositions:

29 + 8670157 = 8670186
59 + 8670127 = 8670186
79 + 8670107 = 8670186
97 + 8670089 = 8670186
149 + 8670037 = 8670186
157 + 8670029 = 8670186
179 + 8670007 = 8670186
193 + 8669993 = 8670186

Showing the first eight; more decompositions exist.
