Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565416, here are decompositions:

5 + 31565411 = 31565416
17 + 31565399 = 31565416
107 + 31565309 = 31565416
137 + 31565279 = 31565416
167 + 31565249 = 31565416
257 + 31565159 = 31565416
347 + 31565069 = 31565416
359 + 31565057 = 31565416

Showing the first eight; more decompositions exist.
