Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533792, here are decompositions:

19 + 31533773 = 31533792
23 + 31533769 = 31533792
29 + 31533763 = 31533792
71 + 31533721 = 31533792
131 + 31533661 = 31533792
151 + 31533641 = 31533792
179 + 31533613 = 31533792
181 + 31533611 = 31533792

Showing the first eight; more decompositions exist.
