Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543204, here are decompositions:

23 + 31543181 = 31543204
41 + 31543163 = 31543204
71 + 31543133 = 31543204
101 + 31543103 = 31543204
137 + 31543067 = 31543204
233 + 31542971 = 31543204
263 + 31542941 = 31543204
293 + 31542911 = 31543204

Showing the first eight; more decompositions exist.
