Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543122, here are decompositions:

19 + 31543103 = 31543122
43 + 31543079 = 31543122
53 + 31543069 = 31543122
103 + 31543019 = 31543122
113 + 31543009 = 31543122
131 + 31542991 = 31543122
151 + 31542971 = 31543122
173 + 31542949 = 31543122

Showing the first eight; more decompositions exist.
