Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548, here are decompositions:

5 + 31543 = 31548
7 + 31541 = 31548
17 + 31531 = 31548
31 + 31517 = 31548
37 + 31511 = 31548
59 + 31489 = 31548
67 + 31481 = 31548
71 + 31477 = 31548

Showing the first eight; more decompositions exist.
