Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554498, here are decompositions:

5 + 31554493 = 31554498
89 + 31554409 = 31554498
97 + 31554401 = 31554498
137 + 31554361 = 31554498
211 + 31554287 = 31554498
257 + 31554241 = 31554498
317 + 31554181 = 31554498
337 + 31554161 = 31554498

Showing the first eight; more decompositions exist.
