Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533470, here are decompositions:

19 + 31533451 = 31533470
61 + 31533409 = 31533470
127 + 31533343 = 31533470
211 + 31533259 = 31533470
337 + 31533133 = 31533470
373 + 31533097 = 31533470
379 + 31533091 = 31533470
457 + 31533013 = 31533470

Showing the first eight; more decompositions exist.
