Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600740, here are decompositions:

7 + 31600733 = 31600740
19 + 31600721 = 31600740
23 + 31600717 = 31600740
37 + 31600703 = 31600740
47 + 31600693 = 31600740
71 + 31600669 = 31600740
191 + 31600549 = 31600740
211 + 31600529 = 31600740

Showing the first eight; more decompositions exist.
