Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624050, here are decompositions:

37 + 31624013 = 31624050
47 + 31624003 = 31624050
61 + 31623989 = 31624050
67 + 31623983 = 31624050
71 + 31623979 = 31624050
79 + 31623971 = 31624050
83 + 31623967 = 31624050
97 + 31623953 = 31624050

Showing the first eight; more decompositions exist.
