Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621154, here are decompositions:

7 + 8621147 = 8621154
11 + 8621143 = 8621154
53 + 8621101 = 8621154
67 + 8621087 = 8621154
71 + 8621083 = 8621154
103 + 8621051 = 8621154
107 + 8621047 = 8621154
137 + 8621017 = 8621154

Showing the first eight; more decompositions exist.
