Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554404, here are decompositions:

3 + 31554401 = 31554404
43 + 31554361 = 31554404
67 + 31554337 = 31554404
163 + 31554241 = 31554404
223 + 31554181 = 31554404
241 + 31554163 = 31554404
283 + 31554121 = 31554404
331 + 31554073 = 31554404

Showing the first eight; more decompositions exist.
