Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543454, here are decompositions:

3 + 31543451 = 31543454
181 + 31543273 = 31543454
211 + 31543243 = 31543454
223 + 31543231 = 31543454
463 + 31542991 = 31543454
487 + 31542967 = 31543454
577 + 31542877 = 31543454
643 + 31542811 = 31543454

Showing the first eight; more decompositions exist.
