Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533262, here are decompositions:

3 + 31533259 = 31533262
53 + 31533209 = 31533262
71 + 31533191 = 31533262
113 + 31533149 = 31533262
263 + 31532999 = 31533262
281 + 31532981 = 31533262
389 + 31532873 = 31533262
569 + 31532693 = 31533262

Showing the first eight; more decompositions exist.
