Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543350, here are decompositions:

19 + 31543331 = 31543350
107 + 31543243 = 31543350
127 + 31543223 = 31543350
131 + 31543219 = 31543350
271 + 31543079 = 31543350
281 + 31543069 = 31543350
283 + 31543067 = 31543350
331 + 31543019 = 31543350

Showing the first eight; more decompositions exist.
