Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533116, here are decompositions:

19 + 31533097 = 31533116
103 + 31533013 = 31533116
157 + 31532959 = 31533116
193 + 31532923 = 31533116
283 + 31532833 = 31533116
367 + 31532749 = 31533116
379 + 31532737 = 31533116
457 + 31532659 = 31533116

Showing the first eight; more decompositions exist.
