Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532418, here are decompositions:

17 + 31532401 = 31532418
79 + 31532339 = 31532418
89 + 31532329 = 31532418
139 + 31532279 = 31532418
149 + 31532269 = 31532418
157 + 31532261 = 31532418
191 + 31532227 = 31532418
199 + 31532219 = 31532418

Showing the first eight; more decompositions exist.
