Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638122, here are decompositions:

5 + 8638117 = 8638122
61 + 8638061 = 8638122
71 + 8638051 = 8638122
79 + 8638043 = 8638122
83 + 8638039 = 8638122
89 + 8638033 = 8638122
131 + 8637991 = 8638122
149 + 8637973 = 8638122

Showing the first eight; more decompositions exist.
