Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502508, here are decompositions:

19 + 31502489 = 31502508
67 + 31502441 = 31502508
137 + 31502371 = 31502508
179 + 31502329 = 31502508
197 + 31502311 = 31502508
229 + 31502279 = 31502508
239 + 31502269 = 31502508
347 + 31502161 = 31502508

Showing the first eight; more decompositions exist.
