Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637138, here are decompositions:

5 + 8637133 = 8637138
7 + 8637131 = 8637138
19 + 8637119 = 8637138
31 + 8637107 = 8637138
47 + 8637091 = 8637138
71 + 8637067 = 8637138
79 + 8637059 = 8637138
131 + 8637007 = 8637138

Showing the first eight; more decompositions exist.
