Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546998, here are decompositions:

11 + 31546987 = 31546998
17 + 31546981 = 31546998
29 + 31546969 = 31546998
61 + 31546937 = 31546998
89 + 31546909 = 31546998
107 + 31546891 = 31546998
137 + 31546861 = 31546998
151 + 31546847 = 31546998

Showing the first eight; more decompositions exist.
