Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637168, here are decompositions:

5 + 8637163 = 8637168
17 + 8637151 = 8637168
37 + 8637131 = 8637168
61 + 8637107 = 8637168
101 + 8637067 = 8637168
107 + 8637061 = 8637168
109 + 8637059 = 8637168
151 + 8637017 = 8637168

Showing the first eight; more decompositions exist.
