Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559356, here are decompositions:

5 + 31559351 = 31559356
137 + 31559219 = 31559356
149 + 31559207 = 31559356
167 + 31559189 = 31559356
263 + 31559093 = 31559356
359 + 31558997 = 31559356
383 + 31558973 = 31559356
509 + 31558847 = 31559356

Showing the first eight; more decompositions exist.
