Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554264, here are decompositions:

23 + 31554241 = 31554264
83 + 31554181 = 31554264
101 + 31554163 = 31554264
103 + 31554161 = 31554264
191 + 31554073 = 31554264
251 + 31554013 = 31554264
271 + 31553993 = 31554264
277 + 31553987 = 31554264

Showing the first eight; more decompositions exist.
