Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533206, here are decompositions:

73 + 31533133 = 31533206
79 + 31533127 = 31533206
109 + 31533097 = 31533206
193 + 31533013 = 31533206
283 + 31532923 = 31533206
307 + 31532899 = 31533206
373 + 31532833 = 31533206
457 + 31532749 = 31533206

Showing the first eight; more decompositions exist.
