Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469000, here are decompositions:

7 + 31468993 = 31469000
37 + 31468963 = 31469000
97 + 31468903 = 31469000
139 + 31468861 = 31469000
151 + 31468849 = 31469000
223 + 31468777 = 31469000
457 + 31468543 = 31469000
547 + 31468453 = 31469000

Showing the first eight; more decompositions exist.
