Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523436, here are decompositions:

17 + 31523419 = 31523436
29 + 31523407 = 31523436
37 + 31523399 = 31523436
89 + 31523347 = 31523436
107 + 31523329 = 31523436
127 + 31523309 = 31523436
157 + 31523279 = 31523436
193 + 31523243 = 31523436

Showing the first eight; more decompositions exist.
