Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634278, here are decompositions:

19 + 8634259 = 8634278
67 + 8634211 = 8634278
109 + 8634169 = 8634278
139 + 8634139 = 8634278
229 + 8634049 = 8634278
307 + 8633971 = 8634278
337 + 8633941 = 8634278
379 + 8633899 = 8634278

Showing the first eight; more decompositions exist.
