Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634940, here are decompositions:

23 + 8634917 = 8634940
59 + 8634881 = 8634940
89 + 8634851 = 8634940
101 + 8634839 = 8634940
137 + 8634803 = 8634940
173 + 8634767 = 8634940
179 + 8634761 = 8634940
227 + 8634713 = 8634940

Showing the first eight; more decompositions exist.
