Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639030, here are decompositions:

3 + 8639027 = 8639030
19 + 8639011 = 8639030
31 + 8638999 = 8639030
79 + 8638951 = 8639030
97 + 8638933 = 8639030
139 + 8638891 = 8639030
163 + 8638867 = 8639030
181 + 8638849 = 8639030

Showing the first eight; more decompositions exist.
