Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543384, here are decompositions:

23 + 31543361 = 31543384
53 + 31543331 = 31543384
83 + 31543301 = 31543384
167 + 31543217 = 31543384
251 + 31543133 = 31543384
281 + 31543103 = 31543384
317 + 31543067 = 31543384
443 + 31542941 = 31543384

Showing the first eight; more decompositions exist.
