Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468434, here are decompositions:

31 + 31468403 = 31468434
37 + 31468397 = 31468434
43 + 31468391 = 31468434
97 + 31468337 = 31468434
103 + 31468331 = 31468434
163 + 31468271 = 31468434
191 + 31468243 = 31468434
211 + 31468223 = 31468434

Showing the first eight; more decompositions exist.
