Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533410, here are decompositions:

31 + 31533379 = 31533410
67 + 31533343 = 31533410
151 + 31533259 = 31533410
277 + 31533133 = 31533410
283 + 31533127 = 31533410
313 + 31533097 = 31533410
397 + 31533013 = 31533410
409 + 31533001 = 31533410

Showing the first eight; more decompositions exist.
