Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533748, here are decompositions:

41 + 31533707 = 31533748
89 + 31533659 = 31533748
107 + 31533641 = 31533748
137 + 31533611 = 31533748
149 + 31533599 = 31533748
167 + 31533581 = 31533748
251 + 31533497 = 31533748
317 + 31533431 = 31533748

Showing the first eight; more decompositions exist.
