Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670618, here are decompositions:

7 + 8670611 = 8670618
29 + 8670589 = 8670618
59 + 8670559 = 8670618
67 + 8670551 = 8670618
109 + 8670509 = 8670618
127 + 8670491 = 8670618
137 + 8670481 = 8670618
167 + 8670451 = 8670618

Showing the first eight; more decompositions exist.
