Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533304, here are decompositions:

113 + 31533191 = 31533304
137 + 31533167 = 31533304
431 + 31532873 = 31533304
617 + 31532687 = 31533304
797 + 31532507 = 31533304
827 + 31532477 = 31533304
1163 + 31532141 = 31533304
1187 + 31532117 = 31533304

Showing the first eight; more decompositions exist.
