Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554344, here are decompositions:

7 + 31554337 = 31554344
61 + 31554283 = 31554344
103 + 31554241 = 31554344
163 + 31554181 = 31554344
181 + 31554163 = 31554344
223 + 31554121 = 31554344
271 + 31554073 = 31554344
331 + 31554013 = 31554344

Showing the first eight; more decompositions exist.
