Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596540, here are decompositions:

29 + 31596511 = 31596540
43 + 31596497 = 31596540
67 + 31596473 = 31596540
103 + 31596437 = 31596540
127 + 31596413 = 31596540
137 + 31596403 = 31596540
139 + 31596401 = 31596540
149 + 31596391 = 31596540

Showing the first eight; more decompositions exist.
