Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469010, here are decompositions:

17 + 31468993 = 31469010
43 + 31468967 = 31469010
47 + 31468963 = 31469010
107 + 31468903 = 31469010
109 + 31468901 = 31469010
149 + 31468861 = 31469010
233 + 31468777 = 31469010
283 + 31468727 = 31469010

Showing the first eight; more decompositions exist.
