Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543414, here are decompositions:

17 + 31543397 = 31543414
53 + 31543361 = 31543414
83 + 31543331 = 31543414
113 + 31543301 = 31543414
191 + 31543223 = 31543414
197 + 31543217 = 31543414
233 + 31543181 = 31543414
251 + 31543163 = 31543414

Showing the first eight; more decompositions exist.
