Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523506, here are decompositions:

29 + 31523477 = 31523506
107 + 31523399 = 31523506
197 + 31523309 = 31523506
227 + 31523279 = 31523506
239 + 31523267 = 31523506
263 + 31523243 = 31523506
269 + 31523237 = 31523506
479 + 31523027 = 31523506

Showing the first eight; more decompositions exist.
