Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553476, here are decompositions:

23 + 31553453 = 31553476
89 + 31553387 = 31553476
107 + 31553369 = 31553476
137 + 31553339 = 31553476
197 + 31553279 = 31553476
257 + 31553219 = 31553476
263 + 31553213 = 31553476
293 + 31553183 = 31553476

Showing the first eight; more decompositions exist.
