Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624104, here are decompositions:

101 + 31624003 = 31624104
103 + 31624001 = 31624104
137 + 31623967 = 31624104
151 + 31623953 = 31624104
157 + 31623947 = 31624104
173 + 31623931 = 31624104
283 + 31623821 = 31624104
307 + 31623797 = 31624104

Showing the first eight; more decompositions exist.
