Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639364, here are decompositions:

17 + 8639347 = 8639364
73 + 8639291 = 8639364
101 + 8639263 = 8639364
103 + 8639261 = 8639364
113 + 8639251 = 8639364
137 + 8639227 = 8639364
157 + 8639207 = 8639364
193 + 8639171 = 8639364

Showing the first eight; more decompositions exist.
