Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502274, here are decompositions:

5 + 31502269 = 31502274
31 + 31502243 = 31502274
61 + 31502213 = 31502274
113 + 31502161 = 31502274
127 + 31502147 = 31502274
191 + 31502083 = 31502274
317 + 31501957 = 31502274
337 + 31501937 = 31502274

Showing the first eight; more decompositions exist.
