Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566044, here are decompositions:

31 + 31566013 = 31566044
43 + 31566001 = 31566044
73 + 31565971 = 31566044
127 + 31565917 = 31566044
157 + 31565887 = 31566044
193 + 31565851 = 31566044
241 + 31565803 = 31566044
283 + 31565761 = 31566044

Showing the first eight; more decompositions exist.
