Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553464, here are decompositions:

11 + 31553453 = 31553464
113 + 31553351 = 31553464
191 + 31553273 = 31553464
251 + 31553213 = 31553464
263 + 31553201 = 31553464
281 + 31553183 = 31553464
401 + 31553063 = 31553464
443 + 31553021 = 31553464

Showing the first eight; more decompositions exist.
