Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523476, here are decompositions:

3 + 31523473 = 31523476
167 + 31523309 = 31523476
197 + 31523279 = 31523476
233 + 31523243 = 31523476
239 + 31523237 = 31523476
269 + 31523207 = 31523476
449 + 31523027 = 31523476
587 + 31522889 = 31523476

Showing the first eight; more decompositions exist.
