Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543618, here are decompositions:

47 + 31543571 = 31543618
89 + 31543529 = 31543618
137 + 31543481 = 31543618
167 + 31543451 = 31543618
257 + 31543361 = 31543618
269 + 31543349 = 31543618
317 + 31543301 = 31543618
401 + 31543217 = 31543618

Showing the first eight; more decompositions exist.
