Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668626, here are decompositions:

13 + 8668613 = 8668626
17 + 8668609 = 8668626
73 + 8668553 = 8668626
79 + 8668547 = 8668626
103 + 8668523 = 8668626
107 + 8668519 = 8668626
137 + 8668489 = 8668626
167 + 8668459 = 8668626

Showing the first eight; more decompositions exist.
