Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621956, here are decompositions:

17 + 8621939 = 8621956
23 + 8621933 = 8621956
29 + 8621927 = 8621956
59 + 8621897 = 8621956
89 + 8621867 = 8621956
113 + 8621843 = 8621956
137 + 8621819 = 8621956
263 + 8621693 = 8621956

Showing the first eight; more decompositions exist.
