Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553334, here are decompositions:

13 + 31553321 = 31553334
61 + 31553273 = 31553334
73 + 31553261 = 31553334
101 + 31553233 = 31553334
151 + 31553183 = 31553334
157 + 31553177 = 31553334
173 + 31553161 = 31553334
257 + 31553077 = 31553334

Showing the first eight; more decompositions exist.
