Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670658, here are decompositions:

5 + 8670653 = 8670658
47 + 8670611 = 8670658
107 + 8670551 = 8670658
149 + 8670509 = 8670658
167 + 8670491 = 8670658
251 + 8670407 = 8670658
401 + 8670257 = 8670658
419 + 8670239 = 8670658

Showing the first eight; more decompositions exist.
