Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624056, here are decompositions:

43 + 31624013 = 31624056
53 + 31624003 = 31624056
67 + 31623989 = 31624056
73 + 31623983 = 31624056
89 + 31623967 = 31624056
97 + 31623959 = 31624056
103 + 31623953 = 31624056
109 + 31623947 = 31624056

Showing the first eight; more decompositions exist.
