Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534740, here are decompositions:

11 + 31534729 = 31534740
31 + 31534709 = 31534740
71 + 31534669 = 31534740
89 + 31534651 = 31534740
103 + 31534637 = 31534740
109 + 31534631 = 31534740
151 + 31534589 = 31534740
179 + 31534561 = 31534740

Showing the first eight; more decompositions exist.
