Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622042, here are decompositions:

19 + 8622023 = 8622042
31 + 8622011 = 8622042
41 + 8622001 = 8622042
53 + 8621989 = 8622042
59 + 8621983 = 8622042
71 + 8621971 = 8622042
83 + 8621959 = 8622042
103 + 8621939 = 8622042

Showing the first eight; more decompositions exist.
