Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533010, here are decompositions:

11 + 31532999 = 31533010
29 + 31532981 = 31533010
71 + 31532939 = 31533010
137 + 31532873 = 31533010
233 + 31532777 = 31533010
317 + 31532693 = 31533010
503 + 31532507 = 31533010
521 + 31532489 = 31533010

Showing the first eight; more decompositions exist.
