Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468470, here are decompositions:

17 + 31468453 = 31468470
23 + 31468447 = 31468470
67 + 31468403 = 31468470
71 + 31468399 = 31468470
73 + 31468397 = 31468470
79 + 31468391 = 31468470
101 + 31468369 = 31468470
139 + 31468331 = 31468470

Showing the first eight; more decompositions exist.
