Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565426, here are decompositions:

3 + 31565423 = 31565426
43 + 31565383 = 31565426
73 + 31565353 = 31565426
103 + 31565323 = 31565426
127 + 31565299 = 31565426
229 + 31565197 = 31565426
307 + 31565119 = 31565426
349 + 31565077 = 31565426

Showing the first eight; more decompositions exist.
