Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599636, here are decompositions:

7 + 31599629 = 31599636
37 + 31599599 = 31599636
73 + 31599563 = 31599636
83 + 31599553 = 31599636
137 + 31599499 = 31599636
149 + 31599487 = 31599636
197 + 31599439 = 31599636
283 + 31599353 = 31599636

Showing the first eight; more decompositions exist.
