Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601000, here are decompositions:

7 + 31600993 = 31601000
31 + 31600969 = 31601000
43 + 31600957 = 31601000
139 + 31600861 = 31601000
157 + 31600843 = 31601000
199 + 31600801 = 31601000
229 + 31600771 = 31601000
283 + 31600717 = 31601000

Showing the first eight; more decompositions exist.
