Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554904, here are decompositions:

5 + 31554899 = 31554904
11 + 31554893 = 31554904
41 + 31554863 = 31554904
53 + 31554851 = 31554904
107 + 31554797 = 31554904
113 + 31554791 = 31554904
233 + 31554671 = 31554904
263 + 31554641 = 31554904

Showing the first eight; more decompositions exist.
