Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535304, here are decompositions:

41 + 31535263 = 31535304
71 + 31535233 = 31535304
131 + 31535173 = 31535304
173 + 31535131 = 31535304
181 + 31535123 = 31535304
191 + 31535113 = 31535304
197 + 31535107 = 31535304
223 + 31535081 = 31535304

Showing the first eight; more decompositions exist.
