Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554094, here are decompositions:

17 + 31554077 = 31554094
83 + 31554011 = 31554094
101 + 31553993 = 31554094
107 + 31553987 = 31554094
191 + 31553903 = 31554094
227 + 31553867 = 31554094
293 + 31553801 = 31554094
311 + 31553783 = 31554094

Showing the first eight; more decompositions exist.
