Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551334, here are decompositions:

5 + 31551329 = 31551334
53 + 31551281 = 31551334
131 + 31551203 = 31551334
173 + 31551161 = 31551334
197 + 31551137 = 31551334
263 + 31551071 = 31551334
467 + 31550867 = 31551334
587 + 31550747 = 31551334

Showing the first eight; more decompositions exist.
