Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543366, here are decompositions:

5 + 31543361 = 31543366
17 + 31543349 = 31543366
149 + 31543217 = 31543366
233 + 31543133 = 31543366
263 + 31543103 = 31543366
347 + 31543019 = 31543366
509 + 31542857 = 31543366
557 + 31542809 = 31543366

Showing the first eight; more decompositions exist.
