Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494460, here are decompositions:

17 + 31494443 = 31494460
29 + 31494431 = 31494460
59 + 31494401 = 31494460
71 + 31494389 = 31494460
113 + 31494347 = 31494460
167 + 31494293 = 31494460
197 + 31494263 = 31494460
281 + 31494179 = 31494460

Showing the first eight; more decompositions exist.
