Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638626, here are decompositions:

5 + 8638621 = 8638626
43 + 8638583 = 8638626
83 + 8638543 = 8638626
109 + 8638517 = 8638626
149 + 8638477 = 8638626
163 + 8638463 = 8638626
173 + 8638453 = 8638626
179 + 8638447 = 8638626

Showing the first eight; more decompositions exist.
