Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507032, here are decompositions:

23 + 31507009 = 31507032
59 + 31506973 = 31507032
83 + 31506949 = 31507032
101 + 31506931 = 31507032
103 + 31506929 = 31507032
191 + 31506841 = 31507032
211 + 31506821 = 31507032
223 + 31506809 = 31507032

Showing the first eight; more decompositions exist.
