Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533146, here are decompositions:

3 + 31533143 = 31533146
13 + 31533133 = 31533146
19 + 31533127 = 31533146
223 + 31532923 = 31533146
283 + 31532863 = 31533146
313 + 31532833 = 31533146
397 + 31532749 = 31533146
409 + 31532737 = 31533146

Showing the first eight; more decompositions exist.
