Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554234, here are decompositions:

53 + 31554181 = 31554234
71 + 31554163 = 31554234
73 + 31554161 = 31554234
113 + 31554121 = 31554234
157 + 31554077 = 31554234
191 + 31554043 = 31554234
223 + 31554011 = 31554234
241 + 31553993 = 31554234

Showing the first eight; more decompositions exist.
