Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634378, here are decompositions:

7 + 8634371 = 8634378
19 + 8634359 = 8634378
31 + 8634347 = 8634378
79 + 8634299 = 8634378
127 + 8634251 = 8634378
167 + 8634211 = 8634378
199 + 8634179 = 8634378
239 + 8634139 = 8634378

Showing the first eight; more decompositions exist.
