Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590080, here are decompositions:

19 + 31590061 = 31590080
43 + 31590037 = 31590080
73 + 31590007 = 31590080
97 + 31589983 = 31590080
103 + 31589977 = 31590080
127 + 31589953 = 31590080
157 + 31589923 = 31590080
211 + 31589869 = 31590080

Showing the first eight; more decompositions exist.
