Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533370, here are decompositions:

101 + 31533269 = 31533370
179 + 31533191 = 31533370
227 + 31533143 = 31533370
251 + 31533119 = 31533370
269 + 31533101 = 31533370
389 + 31532981 = 31533370
431 + 31532939 = 31533370
503 + 31532867 = 31533370

Showing the first eight; more decompositions exist.
