Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553374, here are decompositions:

5 + 31553369 = 31553374
23 + 31553351 = 31553374
53 + 31553321 = 31553374
101 + 31553273 = 31553374
113 + 31553261 = 31553374
173 + 31553201 = 31553374
191 + 31553183 = 31553374
197 + 31553177 = 31553374

Showing the first eight; more decompositions exist.
