Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554348, here are decompositions:

11 + 31554337 = 31554348
61 + 31554287 = 31554348
107 + 31554241 = 31554348
149 + 31554199 = 31554348
167 + 31554181 = 31554348
227 + 31554121 = 31554348
271 + 31554077 = 31554348
337 + 31554011 = 31554348

Showing the first eight; more decompositions exist.
