Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622942, here are decompositions:

19 + 8622923 = 8622942
59 + 8622883 = 8622942
71 + 8622871 = 8622942
89 + 8622853 = 8622942
101 + 8622841 = 8622942
131 + 8622811 = 8622942
149 + 8622793 = 8622942
179 + 8622763 = 8622942

Showing the first eight; more decompositions exist.
