Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565496, here are decompositions:

5 + 31565491 = 31565496
23 + 31565473 = 31565496
59 + 31565437 = 31565496
73 + 31565423 = 31565496
97 + 31565399 = 31565496
113 + 31565383 = 31565496
173 + 31565323 = 31565496
197 + 31565299 = 31565496

Showing the first eight; more decompositions exist.
