Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553484, here are decompositions:

31 + 31553453 = 31553484
97 + 31553387 = 31553484
101 + 31553383 = 31553484
163 + 31553321 = 31553484
211 + 31553273 = 31553484
223 + 31553261 = 31553484
251 + 31553233 = 31553484
271 + 31553213 = 31553484

Showing the first eight; more decompositions exist.
