Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624036, here are decompositions:

23 + 31624013 = 31624036
47 + 31623989 = 31624036
53 + 31623983 = 31624036
83 + 31623953 = 31624036
89 + 31623947 = 31624036
107 + 31623929 = 31624036
149 + 31623887 = 31624036
179 + 31623857 = 31624036

Showing the first eight; more decompositions exist.
