Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527048, here are decompositions:

31 + 31527017 = 31527048
37 + 31527011 = 31527048
107 + 31526941 = 31527048
109 + 31526939 = 31527048
127 + 31526921 = 31527048
149 + 31526899 = 31527048
167 + 31526881 = 31527048
229 + 31526819 = 31527048

Showing the first eight; more decompositions exist.
