Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527108, here are decompositions:

31 + 31527077 = 31527108
61 + 31527047 = 31527108
97 + 31527011 = 31527108
167 + 31526941 = 31527108
181 + 31526927 = 31527108
227 + 31526881 = 31527108
229 + 31526879 = 31527108
317 + 31526791 = 31527108

Showing the first eight; more decompositions exist.
