Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527118, here are decompositions:

11 + 31527107 = 31527118
41 + 31527077 = 31527118
71 + 31527047 = 31527118
101 + 31527017 = 31527118
107 + 31527011 = 31527118
179 + 31526939 = 31527118
191 + 31526927 = 31527118
197 + 31526921 = 31527118

Showing the first eight; more decompositions exist.
