Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536538, here are decompositions:

17 + 31536521 = 31536538
179 + 31536359 = 31536538
191 + 31536347 = 31536538
251 + 31536287 = 31536538
311 + 31536227 = 31536538
521 + 31536017 = 31536538
557 + 31535981 = 31536538
599 + 31535939 = 31536538

Showing the first eight; more decompositions exist.
