Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543008, here are decompositions:

17 + 31542991 = 31543008
37 + 31542971 = 31543008
41 + 31542967 = 31543008
59 + 31542949 = 31543008
67 + 31542941 = 31543008
71 + 31542937 = 31543008
97 + 31542911 = 31543008
127 + 31542881 = 31543008

Showing the first eight; more decompositions exist.
