Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523466, here are decompositions:

5 + 31523461 = 31523466
47 + 31523419 = 31523466
59 + 31523407 = 31523466
67 + 31523399 = 31523466
137 + 31523329 = 31523466
157 + 31523309 = 31523466
173 + 31523293 = 31523466
199 + 31523267 = 31523466

Showing the first eight; more decompositions exist.
