Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469334, here are decompositions:

7 + 31469327 = 31469334
11 + 31469323 = 31469334
31 + 31469303 = 31469334
41 + 31469293 = 31469334
47 + 31469287 = 31469334
137 + 31469197 = 31469334
157 + 31469177 = 31469334
191 + 31469143 = 31469334

Showing the first eight; more decompositions exist.
