Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548164, here are decompositions:

31 + 31548133 = 31548164
61 + 31548103 = 31548164
157 + 31548007 = 31548164
211 + 31547953 = 31548164
313 + 31547851 = 31548164
331 + 31547833 = 31548164
433 + 31547731 = 31548164
457 + 31547707 = 31548164

Showing the first eight; more decompositions exist.
