Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543014, here are decompositions:

5 + 31543009 = 31543014
23 + 31542991 = 31543014
43 + 31542971 = 31543014
47 + 31542967 = 31543014
71 + 31542943 = 31543014
73 + 31542941 = 31543014
103 + 31542911 = 31543014
137 + 31542877 = 31543014

Showing the first eight; more decompositions exist.
