Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628342, here are decompositions:

71 + 8628271 = 8628342
109 + 8628233 = 8628342
139 + 8628203 = 8628342
181 + 8628161 = 8628342
193 + 8628149 = 8628342
211 + 8628131 = 8628342
293 + 8628049 = 8628342
311 + 8628031 = 8628342

Showing the first eight; more decompositions exist.
