Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471498, here are decompositions:

17 + 31471481 = 31471498
29 + 31471469 = 31471498
41 + 31471457 = 31471498
59 + 31471439 = 31471498
101 + 31471397 = 31471498
137 + 31471361 = 31471498
167 + 31471331 = 31471498
281 + 31471217 = 31471498

Showing the first eight; more decompositions exist.
