Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624102, here are decompositions:

89 + 31624013 = 31624102
101 + 31624001 = 31624102
113 + 31623989 = 31624102
131 + 31623971 = 31624102
149 + 31623953 = 31624102
173 + 31623929 = 31624102
281 + 31623821 = 31624102
401 + 31623701 = 31624102

Showing the first eight; more decompositions exist.
