Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624132, here are decompositions:

3 + 31624129 = 31624132
5 + 31624127 = 31624132
131 + 31624001 = 31624132
149 + 31623983 = 31624132
173 + 31623959 = 31624132
179 + 31623953 = 31624132
311 + 31623821 = 31624132
401 + 31623731 = 31624132

Showing the first eight; more decompositions exist.
