Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533374, here are decompositions:

3 + 31533371 = 31533374
31 + 31533343 = 31533374
241 + 31533133 = 31533374
277 + 31533097 = 31533374
283 + 31533091 = 31533374
373 + 31533001 = 31533374
541 + 31532833 = 31533374
787 + 31532587 = 31533374

Showing the first eight; more decompositions exist.
