Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554894, here are decompositions:

5 + 31554889 = 31554894
11 + 31554883 = 31554894
31 + 31554863 = 31554894
43 + 31554851 = 31554894
53 + 31554841 = 31554894
71 + 31554823 = 31554894
83 + 31554811 = 31554894
97 + 31554797 = 31554894

Showing the first eight; more decompositions exist.
