Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527132, here are decompositions:

23 + 31527109 = 31527132
179 + 31526953 = 31527132
191 + 31526941 = 31527132
193 + 31526939 = 31527132
211 + 31526921 = 31527132
229 + 31526903 = 31527132
233 + 31526899 = 31527132
239 + 31526893 = 31527132

Showing the first eight; more decompositions exist.
