Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532268, here are decompositions:

7 + 31532261 = 31532268
41 + 31532227 = 31532268
59 + 31532209 = 31532268
101 + 31532167 = 31532268
127 + 31532141 = 31532268
151 + 31532117 = 31532268
179 + 31532089 = 31532268
197 + 31532071 = 31532268

Showing the first eight; more decompositions exist.
