Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469298, here are decompositions:

5 + 31469293 = 31469298
11 + 31469287 = 31469298
19 + 31469279 = 31469298
59 + 31469239 = 31469298
89 + 31469209 = 31469298
101 + 31469197 = 31469298
167 + 31469131 = 31469298
197 + 31469101 = 31469298

Showing the first eight; more decompositions exist.
