Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624006, here are decompositions:

3 + 31624003 = 31624006
5 + 31624001 = 31624006
17 + 31623989 = 31624006
23 + 31623983 = 31624006
47 + 31623959 = 31624006
53 + 31623953 = 31624006
59 + 31623947 = 31624006
149 + 31623857 = 31624006

Showing the first eight; more decompositions exist.
