Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523668, here are decompositions:

17 + 31523651 = 31523668
89 + 31523579 = 31523668
131 + 31523537 = 31523668
191 + 31523477 = 31523668
227 + 31523441 = 31523668
257 + 31523411 = 31523668
269 + 31523399 = 31523668
359 + 31523309 = 31523668

Showing the first eight; more decompositions exist.
