Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536232, here are decompositions:

5 + 31536227 = 31536232
29 + 31536203 = 31536232
71 + 31536161 = 31536232
131 + 31536101 = 31536232
179 + 31536053 = 31536232
251 + 31535981 = 31536232
293 + 31535939 = 31536232
353 + 31535879 = 31536232

Showing the first eight; more decompositions exist.
