Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621974, here are decompositions:

3 + 8621971 = 8621974
41 + 8621933 = 8621974
47 + 8621927 = 8621974
107 + 8621867 = 8621974
113 + 8621861 = 8621974
131 + 8621843 = 8621974
227 + 8621747 = 8621974
281 + 8621693 = 8621974

Showing the first eight; more decompositions exist.
