Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548342, here are decompositions:

11 + 31548331 = 31548342
19 + 31548323 = 31548342
29 + 31548313 = 31548342
41 + 31548301 = 31548342
43 + 31548299 = 31548342
61 + 31548281 = 31548342
73 + 31548269 = 31548342
79 + 31548263 = 31548342

Showing the first eight; more decompositions exist.
