Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534828, here are decompositions:

29 + 31534799 = 31534828
41 + 31534787 = 31534828
71 + 31534757 = 31534828
89 + 31534739 = 31534828
137 + 31534691 = 31534828
191 + 31534637 = 31534828
197 + 31534631 = 31534828
239 + 31534589 = 31534828

Showing the first eight; more decompositions exist.
