Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670086, here are decompositions:

79 + 8670007 = 8670086
97 + 8669989 = 8670086
157 + 8669929 = 8670086
163 + 8669923 = 8670086
193 + 8669893 = 8670086
457 + 8669629 = 8670086
463 + 8669623 = 8670086
643 + 8669443 = 8670086

Showing the first eight; more decompositions exist.
