Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600874, here are decompositions:

13 + 31600861 = 31600874
31 + 31600843 = 31600874
73 + 31600801 = 31600874
103 + 31600771 = 31600874
157 + 31600717 = 31600874
181 + 31600693 = 31600874
211 + 31600663 = 31600874
421 + 31600453 = 31600874

Showing the first eight; more decompositions exist.
