Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543116, here are decompositions:

13 + 31543103 = 31543116
37 + 31543079 = 31543116
47 + 31543069 = 31543116
97 + 31543019 = 31543116
107 + 31543009 = 31543116
149 + 31542967 = 31543116
167 + 31542949 = 31543116
173 + 31542943 = 31543116

Showing the first eight; more decompositions exist.
