Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471350, here are decompositions:

19 + 31471331 = 31471350
61 + 31471289 = 31471350
137 + 31471213 = 31471350
179 + 31471171 = 31471350
227 + 31471123 = 31471350
241 + 31471109 = 31471350
257 + 31471093 = 31471350
271 + 31471079 = 31471350

Showing the first eight; more decompositions exist.
