Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624000, here are decompositions:

11 + 31623989 = 31624000
17 + 31623983 = 31624000
29 + 31623971 = 31624000
41 + 31623959 = 31624000
47 + 31623953 = 31624000
53 + 31623947 = 31624000
71 + 31623929 = 31624000
113 + 31623887 = 31624000

Showing the first eight; more decompositions exist.
