Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469022, here are decompositions:

29 + 31468993 = 31469022
59 + 31468963 = 31469022
103 + 31468919 = 31469022
173 + 31468849 = 31469022
199 + 31468823 = 31469022
229 + 31468793 = 31469022
433 + 31468589 = 31469022
449 + 31468573 = 31469022

Showing the first eight; more decompositions exist.
