Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527028, here are decompositions:

11 + 31527017 = 31527028
17 + 31527011 = 31527028
89 + 31526939 = 31527028
101 + 31526927 = 31527028
107 + 31526921 = 31527028
149 + 31526879 = 31527028
251 + 31526777 = 31527028
257 + 31526771 = 31527028

Showing the first eight; more decompositions exist.
