Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600044, here are decompositions:

5 + 31600039 = 31600044
43 + 31600001 = 31600044
67 + 31599977 = 31600044
103 + 31599941 = 31600044
127 + 31599917 = 31600044
131 + 31599913 = 31600044
167 + 31599877 = 31600044
173 + 31599871 = 31600044

Showing the first eight; more decompositions exist.
