Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535884, here are decompositions:

5 + 31535879 = 31535884
53 + 31535831 = 31535884
131 + 31535753 = 31535884
137 + 31535747 = 31535884
167 + 31535717 = 31535884
227 + 31535657 = 31535884
251 + 31535633 = 31535884
293 + 31535591 = 31535884

Showing the first eight; more decompositions exist.
