Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469070, here are decompositions:

29 + 31469041 = 31469070
37 + 31469033 = 31469070
43 + 31469027 = 31469070
103 + 31468967 = 31469070
107 + 31468963 = 31469070
151 + 31468919 = 31469070
167 + 31468903 = 31469070
277 + 31468793 = 31469070

Showing the first eight; more decompositions exist.
