Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590050, here are decompositions:

13 + 31590037 = 31590050
43 + 31590007 = 31590050
67 + 31589983 = 31590050
73 + 31589977 = 31590050
97 + 31589953 = 31590050
127 + 31589923 = 31590050
181 + 31589869 = 31590050
223 + 31589827 = 31590050

Showing the first eight; more decompositions exist.
