Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532364, here are decompositions:

11 + 31532353 = 31532364
23 + 31532341 = 31532364
41 + 31532323 = 31532364
103 + 31532261 = 31532364
137 + 31532227 = 31532364
197 + 31532167 = 31532364
223 + 31532141 = 31532364
251 + 31532113 = 31532364

Showing the first eight; more decompositions exist.
