Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543048, here are decompositions:

29 + 31543019 = 31543048
107 + 31542941 = 31543048
137 + 31542911 = 31543048
167 + 31542881 = 31543048
191 + 31542857 = 31543048
239 + 31542809 = 31543048
281 + 31542767 = 31543048
389 + 31542659 = 31543048

Showing the first eight; more decompositions exist.
