Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543068, here are decompositions:

59 + 31543009 = 31543068
97 + 31542971 = 31543068
101 + 31542967 = 31543068
127 + 31542941 = 31543068
131 + 31542937 = 31543068
157 + 31542911 = 31543068
191 + 31542877 = 31543068
211 + 31542857 = 31543068

Showing the first eight; more decompositions exist.
