Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543024, here are decompositions:

5 + 31543019 = 31543024
53 + 31542971 = 31543024
83 + 31542941 = 31543024
113 + 31542911 = 31543024
167 + 31542857 = 31543024
197 + 31542827 = 31543024
257 + 31542767 = 31543024
347 + 31542677 = 31543024

Showing the first eight; more decompositions exist.
