Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483888, here are decompositions:

5 + 31483883 = 31483888
11 + 31483877 = 31483888
17 + 31483871 = 31483888
47 + 31483841 = 31483888
89 + 31483799 = 31483888
197 + 31483691 = 31483888
239 + 31483649 = 31483888
311 + 31483577 = 31483888

Showing the first eight; more decompositions exist.
