Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543396, here are decompositions:

47 + 31543349 = 31543396
173 + 31543223 = 31543396
179 + 31543217 = 31543396
233 + 31543163 = 31543396
263 + 31543133 = 31543396
293 + 31543103 = 31543396
317 + 31543079 = 31543396
569 + 31542827 = 31543396

Showing the first eight; more decompositions exist.
