Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554912, here are decompositions:

13 + 31554899 = 31554912
19 + 31554893 = 31554912
23 + 31554889 = 31554912
29 + 31554883 = 31554912
61 + 31554851 = 31554912
71 + 31554841 = 31554912
83 + 31554829 = 31554912
89 + 31554823 = 31554912

Showing the first eight; more decompositions exist.
