Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536028, here are decompositions:

11 + 31536017 = 31536028
47 + 31535981 = 31536028
89 + 31535939 = 31536028
149 + 31535879 = 31536028
197 + 31535831 = 31536028
281 + 31535747 = 31536028
311 + 31535717 = 31536028
347 + 31535681 = 31536028

Showing the first eight; more decompositions exist.
