Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523410, here are decompositions:

3 + 31523407 = 31523410
11 + 31523399 = 31523410
29 + 31523381 = 31523410
101 + 31523309 = 31523410
131 + 31523279 = 31523410
167 + 31523243 = 31523410
173 + 31523237 = 31523410
179 + 31523231 = 31523410

Showing the first eight; more decompositions exist.
