Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553344, here are decompositions:

5 + 31553339 = 31553344
23 + 31553321 = 31553344
71 + 31553273 = 31553344
83 + 31553261 = 31553344
131 + 31553213 = 31553344
167 + 31553177 = 31553344
281 + 31553063 = 31553344
401 + 31552943 = 31553344

Showing the first eight; more decompositions exist.
