Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622078, here are decompositions:

7 + 8622071 = 8622078
37 + 8622041 = 8622078
61 + 8622017 = 8622078
67 + 8622011 = 8622078
71 + 8622007 = 8622078
89 + 8621989 = 8622078
107 + 8621971 = 8622078
131 + 8621947 = 8622078

Showing the first eight; more decompositions exist.
