Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624026, here are decompositions:

13 + 31624013 = 31624026
23 + 31624003 = 31624026
37 + 31623989 = 31624026
43 + 31623983 = 31624026
47 + 31623979 = 31624026
59 + 31623967 = 31624026
67 + 31623959 = 31624026
73 + 31623953 = 31624026

Showing the first eight; more decompositions exist.
