Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502466, here are decompositions:

7 + 31502459 = 31502466
103 + 31502363 = 31502466
113 + 31502353 = 31502466
137 + 31502329 = 31502466
179 + 31502287 = 31502466
197 + 31502269 = 31502466
223 + 31502243 = 31502466
277 + 31502189 = 31502466

Showing the first eight; more decompositions exist.
