Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554124, here are decompositions:

3 + 31554121 = 31554124
47 + 31554077 = 31554124
113 + 31554011 = 31554124
131 + 31553993 = 31554124
137 + 31553987 = 31554124
257 + 31553867 = 31554124
317 + 31553807 = 31554124
347 + 31553777 = 31554124

Showing the first eight; more decompositions exist.
