Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553506, here are decompositions:

3 + 31553503 = 31553506
53 + 31553453 = 31553506
137 + 31553369 = 31553506
167 + 31553339 = 31553506
227 + 31553279 = 31553506
233 + 31553273 = 31553506
293 + 31553213 = 31553506
443 + 31553063 = 31553506

Showing the first eight; more decompositions exist.
