Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638200, here are decompositions:

13 + 8638187 = 8638200
17 + 8638183 = 8638200
61 + 8638139 = 8638200
79 + 8638121 = 8638200
83 + 8638117 = 8638200
139 + 8638061 = 8638200
149 + 8638051 = 8638200
157 + 8638043 = 8638200

Showing the first eight; more decompositions exist.
