Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543304, here are decompositions:

3 + 31543301 = 31543304
31 + 31543273 = 31543304
61 + 31543243 = 31543304
73 + 31543231 = 31543304
97 + 31543207 = 31543304
313 + 31542991 = 31543304
337 + 31542967 = 31543304
367 + 31542937 = 31543304

Showing the first eight; more decompositions exist.
