Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543032, here are decompositions:

13 + 31543019 = 31543032
23 + 31543009 = 31543032
41 + 31542991 = 31543032
61 + 31542971 = 31543032
83 + 31542949 = 31543032
89 + 31542943 = 31543032
151 + 31542881 = 31543032
223 + 31542809 = 31543032

Showing the first eight; more decompositions exist.
