Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554966, here are decompositions:

5 + 31554961 = 31554966
17 + 31554949 = 31554966
19 + 31554947 = 31554966
67 + 31554899 = 31554966
73 + 31554893 = 31554966
83 + 31554883 = 31554966
103 + 31554863 = 31554966
137 + 31554829 = 31554966

Showing the first eight; more decompositions exist.
