Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543038, here are decompositions:

19 + 31543019 = 31543038
29 + 31543009 = 31543038
47 + 31542991 = 31543038
67 + 31542971 = 31543038
71 + 31542967 = 31543038
89 + 31542949 = 31543038
97 + 31542941 = 31543038
101 + 31542937 = 31543038

Showing the first eight; more decompositions exist.
