Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543010, here are decompositions:

19 + 31542991 = 31543010
43 + 31542967 = 31543010
61 + 31542949 = 31543010
67 + 31542943 = 31543010
73 + 31542937 = 31543010
181 + 31542829 = 31543010
199 + 31542811 = 31543010
211 + 31542799 = 31543010

Showing the first eight; more decompositions exist.
