Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565366, here are decompositions:

13 + 31565353 = 31565366
43 + 31565323 = 31565366
67 + 31565299 = 31565366
73 + 31565293 = 31565366
109 + 31565257 = 31565366
193 + 31565173 = 31565366
199 + 31565167 = 31565366
337 + 31565029 = 31565366

Showing the first eight; more decompositions exist.
