Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567044, here are decompositions:

71 + 31566973 = 31567044
181 + 31566863 = 31567044
227 + 31566817 = 31567044
241 + 31566803 = 31567044
251 + 31566793 = 31567044
281 + 31566763 = 31567044
307 + 31566737 = 31567044
331 + 31566713 = 31567044

Showing the first eight; more decompositions exist.
