Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446048, here are decompositions:

17 + 31446031 = 31446048
37 + 31446011 = 31446048
71 + 31445977 = 31446048
89 + 31445959 = 31446048
107 + 31445941 = 31446048
131 + 31445917 = 31446048
157 + 31445891 = 31446048
197 + 31445851 = 31446048

Showing the first eight; more decompositions exist.
