Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548374, here are decompositions:

31 + 31548343 = 31548374
43 + 31548331 = 31548374
61 + 31548313 = 31548374
73 + 31548301 = 31548374
241 + 31548133 = 31548374
271 + 31548103 = 31548374
367 + 31548007 = 31548374
421 + 31547953 = 31548374

Showing the first eight; more decompositions exist.
