Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468406, here are decompositions:

3 + 31468403 = 31468406
7 + 31468399 = 31468406
37 + 31468369 = 31468406
163 + 31468243 = 31468406
379 + 31468027 = 31468406
439 + 31467967 = 31468406
457 + 31467949 = 31468406
577 + 31467829 = 31468406

Showing the first eight; more decompositions exist.
