Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600050, here are decompositions:

7 + 31600043 = 31600050
11 + 31600039 = 31600050
73 + 31599977 = 31600050
109 + 31599941 = 31600050
137 + 31599913 = 31600050
149 + 31599901 = 31600050
173 + 31599877 = 31600050
179 + 31599871 = 31600050

Showing the first eight; more decompositions exist.
