Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624012, here are decompositions:

11 + 31624001 = 31624012
23 + 31623989 = 31624012
29 + 31623983 = 31624012
41 + 31623971 = 31624012
53 + 31623959 = 31624012
59 + 31623953 = 31624012
83 + 31623929 = 31624012
191 + 31623821 = 31624012

Showing the first eight; more decompositions exist.
