Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546994, here are decompositions:

7 + 31546987 = 31546994
13 + 31546981 = 31546994
103 + 31546891 = 31546994
151 + 31546843 = 31546994
163 + 31546831 = 31546994
181 + 31546813 = 31546994
277 + 31546717 = 31546994
331 + 31546663 = 31546994

Showing the first eight; more decompositions exist.
