Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533378, here are decompositions:

7 + 31533371 = 31533378
109 + 31533269 = 31533378
211 + 31533167 = 31533378
229 + 31533149 = 31533378
251 + 31533127 = 31533378
277 + 31533101 = 31533378
281 + 31533097 = 31533378
379 + 31532999 = 31533378

Showing the first eight; more decompositions exist.
