Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535268, here are decompositions:

5 + 31535263 = 31535268
41 + 31535227 = 31535268
97 + 31535171 = 31535268
137 + 31535131 = 31535268
211 + 31535057 = 31535268
257 + 31535011 = 31535268
269 + 31534999 = 31535268
307 + 31534961 = 31535268

Showing the first eight; more decompositions exist.
