Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535356, here are decompositions:

29 + 31535327 = 31535356
137 + 31535219 = 31535356
173 + 31535183 = 31535356
233 + 31535123 = 31535356
443 + 31534913 = 31535356
557 + 31534799 = 31535356
569 + 31534787 = 31535356
599 + 31534757 = 31535356

Showing the first eight; more decompositions exist.
