Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502482, here are decompositions:

23 + 31502459 = 31502482
41 + 31502441 = 31502482
149 + 31502333 = 31502482
239 + 31502243 = 31502482
269 + 31502213 = 31502482
293 + 31502189 = 31502482
353 + 31502129 = 31502482
383 + 31502099 = 31502482

Showing the first eight; more decompositions exist.
