Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533044, here are decompositions:

31 + 31533013 = 31533044
43 + 31533001 = 31533044
73 + 31532971 = 31533044
163 + 31532881 = 31533044
181 + 31532863 = 31533044
211 + 31532833 = 31533044
307 + 31532737 = 31533044
457 + 31532587 = 31533044

Showing the first eight; more decompositions exist.
