Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533472, here are decompositions:

11 + 31533461 = 31533472
23 + 31533449 = 31533472
41 + 31533431 = 31533472
59 + 31533413 = 31533472
83 + 31533389 = 31533472
101 + 31533371 = 31533472
263 + 31533209 = 31533472
281 + 31533191 = 31533472

Showing the first eight; more decompositions exist.
