Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639344, here are decompositions:

53 + 8639291 = 8639344
71 + 8639273 = 8639344
83 + 8639261 = 8639344
137 + 8639207 = 8639344
167 + 8639177 = 8639344
173 + 8639171 = 8639344
191 + 8639153 = 8639344
281 + 8639063 = 8639344

Showing the first eight; more decompositions exist.
