Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576360, here are decompositions:

71 + 31576289 = 31576360
107 + 31576253 = 31576360
149 + 31576211 = 31576360
173 + 31576187 = 31576360
191 + 31576169 = 31576360
197 + 31576163 = 31576360
239 + 31576121 = 31576360
269 + 31576091 = 31576360

Showing the first eight; more decompositions exist.
