Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536288, here are decompositions:

61 + 31536227 = 31536288
101 + 31536187 = 31536288
127 + 31536161 = 31536288
191 + 31536097 = 31536288
227 + 31536061 = 31536288
239 + 31536049 = 31536288
269 + 31536019 = 31536288
271 + 31536017 = 31536288

Showing the first eight; more decompositions exist.
