Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620344, here are decompositions:

17 + 8620327 = 8620344
37 + 8620307 = 8620344
67 + 8620277 = 8620344
113 + 8620231 = 8620344
127 + 8620217 = 8620344
157 + 8620187 = 8620344
193 + 8620151 = 8620344
211 + 8620133 = 8620344

Showing the first eight; more decompositions exist.
