Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543150, here are decompositions:

17 + 31543133 = 31543150
47 + 31543103 = 31543150
71 + 31543079 = 31543150
83 + 31543067 = 31543150
131 + 31543019 = 31543150
179 + 31542971 = 31543150
239 + 31542911 = 31543150
269 + 31542881 = 31543150

Showing the first eight; more decompositions exist.
