Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471362, here are decompositions:

5 + 31471357 = 31471362
31 + 31471331 = 31471362
73 + 31471289 = 31471362
149 + 31471213 = 31471362
191 + 31471171 = 31471362
239 + 31471123 = 31471362
269 + 31471093 = 31471362
271 + 31471091 = 31471362

Showing the first eight; more decompositions exist.
