Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471482, here are decompositions:

13 + 31471469 = 31471482
43 + 31471439 = 31471482
71 + 31471411 = 31471482
109 + 31471373 = 31471482
151 + 31471331 = 31471482
193 + 31471289 = 31471482
269 + 31471213 = 31471482
311 + 31471171 = 31471482

Showing the first eight; more decompositions exist.
