Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588072, here are decompositions:

11 + 31588061 = 31588072
53 + 31588019 = 31588072
149 + 31587923 = 31588072
179 + 31587893 = 31588072
293 + 31587779 = 31588072
449 + 31587623 = 31588072
563 + 31587509 = 31588072
599 + 31587473 = 31588072

Showing the first eight; more decompositions exist.
