Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523376, here are decompositions:

29 + 31523347 = 31523376
47 + 31523329 = 31523376
67 + 31523309 = 31523376
83 + 31523293 = 31523376
97 + 31523279 = 31523376
109 + 31523267 = 31523376
139 + 31523237 = 31523376
149 + 31523227 = 31523376

Showing the first eight; more decompositions exist.
