Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554270, here are decompositions:

29 + 31554241 = 31554270
71 + 31554199 = 31554270
89 + 31554181 = 31554270
107 + 31554163 = 31554270
109 + 31554161 = 31554270
127 + 31554143 = 31554270
149 + 31554121 = 31554270
193 + 31554077 = 31554270

Showing the first eight; more decompositions exist.
