Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638050, here are decompositions:

7 + 8638043 = 8638050
11 + 8638039 = 8638050
17 + 8638033 = 8638050
59 + 8637991 = 8638050
97 + 8637953 = 8638050
107 + 8637943 = 8638050
181 + 8637869 = 8638050
229 + 8637821 = 8638050

Showing the first eight; more decompositions exist.
