Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530054, here are decompositions:

11 + 31530043 = 31530054
37 + 31530017 = 31530054
53 + 31530001 = 31530054
131 + 31529923 = 31530054
163 + 31529891 = 31530054
173 + 31529881 = 31530054
211 + 31529843 = 31530054
271 + 31529783 = 31530054

Showing the first eight; more decompositions exist.
