Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554276, here are decompositions:

97 + 31554179 = 31554276
113 + 31554163 = 31554276
199 + 31554077 = 31554276
233 + 31554043 = 31554276
263 + 31554013 = 31554276
283 + 31553993 = 31554276
293 + 31553983 = 31554276
373 + 31553903 = 31554276

Showing the first eight; more decompositions exist.
