Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601072, here are decompositions:

31 + 31601041 = 31601072
79 + 31600993 = 31601072
103 + 31600969 = 31601072
211 + 31600861 = 31601072
229 + 31600843 = 31601072
271 + 31600801 = 31601072
331 + 31600741 = 31601072
379 + 31600693 = 31601072

Showing the first eight; more decompositions exist.
