Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469046, here are decompositions:

5 + 31469041 = 31469046
13 + 31469033 = 31469046
19 + 31469027 = 31469046
53 + 31468993 = 31469046
79 + 31468967 = 31469046
83 + 31468963 = 31469046
127 + 31468919 = 31469046
197 + 31468849 = 31469046

Showing the first eight; more decompositions exist.
