Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601058, here are decompositions:

7 + 31601051 = 31601058
17 + 31601041 = 31601058
89 + 31600969 = 31601058
101 + 31600957 = 31601058
197 + 31600861 = 31601058
199 + 31600859 = 31601058
241 + 31600817 = 31601058
257 + 31600801 = 31601058

Showing the first eight; more decompositions exist.
