Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502298, here are decompositions:

11 + 31502287 = 31502298
19 + 31502279 = 31502298
29 + 31502269 = 31502298
109 + 31502189 = 31502298
137 + 31502161 = 31502298
151 + 31502147 = 31502298
167 + 31502131 = 31502298
199 + 31502099 = 31502298

Showing the first eight; more decompositions exist.
