Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607418, here are decompositions:

19 + 31607399 = 31607418
61 + 31607357 = 31607418
109 + 31607309 = 31607418
127 + 31607291 = 31607418
137 + 31607281 = 31607418
181 + 31607237 = 31607418
191 + 31607227 = 31607418
211 + 31607207 = 31607418

Showing the first eight; more decompositions exist.
