Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523496, here are decompositions:

19 + 31523477 = 31523496
23 + 31523473 = 31523496
29 + 31523467 = 31523496
89 + 31523407 = 31523496
97 + 31523399 = 31523496
149 + 31523347 = 31523496
167 + 31523329 = 31523496
229 + 31523267 = 31523496

Showing the first eight; more decompositions exist.
