Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543874, here are decompositions:

3 + 31543871 = 31543874
31 + 31543843 = 31543874
97 + 31543777 = 31543874
151 + 31543723 = 31543874
163 + 31543711 = 31543874
331 + 31543543 = 31543874
421 + 31543453 = 31543874
601 + 31543273 = 31543874

Showing the first eight; more decompositions exist.
