Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553524, here are decompositions:

5 + 31553519 = 31553524
71 + 31553453 = 31553524
137 + 31553387 = 31553524
173 + 31553351 = 31553524
251 + 31553273 = 31553524
263 + 31553261 = 31553524
311 + 31553213 = 31553524
347 + 31553177 = 31553524

Showing the first eight; more decompositions exist.
