Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546992, here are decompositions:

5 + 31546987 = 31546992
11 + 31546981 = 31546992
23 + 31546969 = 31546992
79 + 31546913 = 31546992
83 + 31546909 = 31546992
101 + 31546891 = 31546992
131 + 31546861 = 31546992
149 + 31546843 = 31546992

Showing the first eight; more decompositions exist.
