Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534304, here are decompositions:

3 + 31534301 = 31534304
7 + 31534297 = 31534304
73 + 31534231 = 31534304
163 + 31534141 = 31534304
271 + 31534033 = 31534304
337 + 31533967 = 31534304
433 + 31533871 = 31534304
457 + 31533847 = 31534304

Showing the first eight; more decompositions exist.
