Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507234, here are decompositions:

23 + 31507211 = 31507234
53 + 31507181 = 31507234
197 + 31507037 = 31507234
257 + 31506977 = 31507234
347 + 31506887 = 31507234
443 + 31506791 = 31507234
491 + 31506743 = 31507234
557 + 31506677 = 31507234

Showing the first eight; more decompositions exist.
