Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527208, here are decompositions:

17 + 31527191 = 31527208
59 + 31527149 = 31527208
101 + 31527107 = 31527208
131 + 31527077 = 31527208
191 + 31527017 = 31527208
197 + 31527011 = 31527208
269 + 31526939 = 31527208
281 + 31526927 = 31527208

Showing the first eight; more decompositions exist.
