Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548768, here are decompositions:

5 + 31548763 = 31548768
11 + 31548757 = 31548768
19 + 31548749 = 31548768
29 + 31548739 = 31548768
71 + 31548697 = 31548768
109 + 31548659 = 31548768
127 + 31548641 = 31548768
149 + 31548619 = 31548768

Showing the first eight; more decompositions exist.
