Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543174, here are decompositions:

11 + 31543163 = 31543174
41 + 31543133 = 31543174
71 + 31543103 = 31543174
107 + 31543067 = 31543174
233 + 31542941 = 31543174
263 + 31542911 = 31543174
293 + 31542881 = 31543174
317 + 31542857 = 31543174

Showing the first eight; more decompositions exist.
