Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548828, here are decompositions:

5 + 31548823 = 31548828
11 + 31548817 = 31548828
61 + 31548767 = 31548828
71 + 31548757 = 31548828
79 + 31548749 = 31548828
89 + 31548739 = 31548828
131 + 31548697 = 31548828
151 + 31548677 = 31548828

Showing the first eight; more decompositions exist.
