Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638062, here are decompositions:

11 + 8638051 = 8638062
19 + 8638043 = 8638062
23 + 8638039 = 8638062
29 + 8638033 = 8638062
71 + 8637991 = 8638062
89 + 8637973 = 8638062
109 + 8637953 = 8638062
193 + 8637869 = 8638062

Showing the first eight; more decompositions exist.
