Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609044, here are decompositions:

11 + 31609033 = 31609044
13 + 31609031 = 31609044
73 + 31608971 = 31609044
107 + 31608937 = 31609044
127 + 31608917 = 31609044
151 + 31608893 = 31609044
157 + 31608887 = 31609044
191 + 31608853 = 31609044

Showing the first eight; more decompositions exist.
