Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469396, here are decompositions:

43 + 31469353 = 31469396
73 + 31469323 = 31469396
97 + 31469299 = 31469396
103 + 31469293 = 31469396
109 + 31469287 = 31469396
157 + 31469239 = 31469396
199 + 31469197 = 31469396
433 + 31468963 = 31469396

Showing the first eight; more decompositions exist.
