Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543254, here are decompositions:

11 + 31543243 = 31543254
23 + 31543231 = 31543254
31 + 31543223 = 31543254
37 + 31543217 = 31543254
47 + 31543207 = 31543254
73 + 31543181 = 31543254
151 + 31543103 = 31543254
263 + 31542991 = 31543254

Showing the first eight; more decompositions exist.
