Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637144, here are decompositions:

11 + 8637133 = 8637144
13 + 8637131 = 8637144
37 + 8637107 = 8637144
41 + 8637103 = 8637144
53 + 8637091 = 8637144
83 + 8637061 = 8637144
127 + 8637017 = 8637144
137 + 8637007 = 8637144

Showing the first eight; more decompositions exist.
