Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468908, here are decompositions:

5 + 31468903 = 31468908
7 + 31468901 = 31468908
47 + 31468861 = 31468908
59 + 31468849 = 31468908
131 + 31468777 = 31468908
151 + 31468757 = 31468908
181 + 31468727 = 31468908
241 + 31468667 = 31468908

Showing the first eight; more decompositions exist.
