Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624030, here are decompositions:

17 + 31624013 = 31624030
29 + 31624001 = 31624030
41 + 31623989 = 31624030
47 + 31623983 = 31624030
59 + 31623971 = 31624030
71 + 31623959 = 31624030
83 + 31623947 = 31624030
101 + 31623929 = 31624030

Showing the first eight; more decompositions exist.
