Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639258, here are decompositions:

7 + 8639251 = 8639258
31 + 8639227 = 8639258
97 + 8639161 = 8639258
109 + 8639149 = 8639258
127 + 8639131 = 8639258
139 + 8639119 = 8639258
151 + 8639107 = 8639258
307 + 8638951 = 8639258

Showing the first eight; more decompositions exist.
