Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554144, here are decompositions:

23 + 31554121 = 31554144
67 + 31554077 = 31554144
71 + 31554073 = 31554144
101 + 31554043 = 31554144
131 + 31554013 = 31554144
151 + 31553993 = 31554144
157 + 31553987 = 31554144
241 + 31553903 = 31554144

Showing the first eight; more decompositions exist.
