Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554366, here are decompositions:

5 + 31554361 = 31554366
29 + 31554337 = 31554366
79 + 31554287 = 31554366
83 + 31554283 = 31554366
167 + 31554199 = 31554366
223 + 31554143 = 31554366
293 + 31554073 = 31554366
353 + 31554013 = 31554366

Showing the first eight; more decompositions exist.
