Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639342, here are decompositions:

43 + 8639299 = 8639342
79 + 8639263 = 8639342
181 + 8639161 = 8639342
193 + 8639149 = 8639342
199 + 8639143 = 8639342
211 + 8639131 = 8639342
223 + 8639119 = 8639342
331 + 8639011 = 8639342

Showing the first eight; more decompositions exist.
