Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533874, here are decompositions:

3 + 31533871 = 31533874
41 + 31533833 = 31533874
83 + 31533791 = 31533874
101 + 31533773 = 31533874
167 + 31533707 = 31533874
233 + 31533641 = 31533874
263 + 31533611 = 31533874
293 + 31533581 = 31533874

Showing the first eight; more decompositions exist.
