Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523606, here are decompositions:

7 + 31523599 = 31523606
67 + 31523539 = 31523606
139 + 31523467 = 31523606
199 + 31523407 = 31523606
277 + 31523329 = 31523606
313 + 31523293 = 31523606
379 + 31523227 = 31523606
397 + 31523209 = 31523606

Showing the first eight; more decompositions exist.
