Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622072, here are decompositions:

31 + 8622041 = 8622072
61 + 8622011 = 8622072
71 + 8622001 = 8622072
83 + 8621989 = 8622072
89 + 8621983 = 8622072
101 + 8621971 = 8622072
113 + 8621959 = 8622072
139 + 8621933 = 8622072

Showing the first eight; more decompositions exist.
