Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533444, here are decompositions:

13 + 31533431 = 31533444
31 + 31533413 = 31533444
73 + 31533371 = 31533444
101 + 31533343 = 31533444
277 + 31533167 = 31533444
311 + 31533133 = 31533444
317 + 31533127 = 31533444
347 + 31533097 = 31533444

Showing the first eight; more decompositions exist.
