Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534896, here are decompositions:

17 + 31534879 = 31534896
23 + 31534873 = 31534896
97 + 31534799 = 31534896
109 + 31534787 = 31534896
139 + 31534757 = 31534896
157 + 31534739 = 31534896
167 + 31534729 = 31534896
227 + 31534669 = 31534896

Showing the first eight; more decompositions exist.
