Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543422, here are decompositions:

61 + 31543361 = 31543422
73 + 31543349 = 31543422
149 + 31543273 = 31543422
179 + 31543243 = 31543422
191 + 31543231 = 31543422
199 + 31543223 = 31543422
241 + 31543181 = 31543422
353 + 31543069 = 31543422

Showing the first eight; more decompositions exist.
