Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565606, here are decompositions:

3 + 31565603 = 31565606
67 + 31565539 = 31565606
109 + 31565497 = 31565606
223 + 31565383 = 31565606
229 + 31565377 = 31565606
283 + 31565323 = 31565606
307 + 31565299 = 31565606
313 + 31565293 = 31565606

Showing the first eight; more decompositions exist.
