Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533482, here are decompositions:

31 + 31533451 = 31533482
73 + 31533409 = 31533482
103 + 31533379 = 31533482
139 + 31533343 = 31533482
223 + 31533259 = 31533482
349 + 31533133 = 31533482
523 + 31532959 = 31533482
601 + 31532881 = 31533482

Showing the first eight; more decompositions exist.
