Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469004, here are decompositions:

11 + 31468993 = 31469004
37 + 31468967 = 31469004
41 + 31468963 = 31469004
101 + 31468903 = 31469004
103 + 31468901 = 31469004
181 + 31468823 = 31469004
211 + 31468793 = 31469004
227 + 31468777 = 31469004

Showing the first eight; more decompositions exist.
