Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463472, here are decompositions:

13 + 31463459 = 31463472
43 + 31463429 = 31463472
83 + 31463389 = 31463472
109 + 31463363 = 31463472
151 + 31463321 = 31463472
191 + 31463281 = 31463472
211 + 31463261 = 31463472
223 + 31463249 = 31463472

Showing the first eight; more decompositions exist.
