Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553398, here are decompositions:

11 + 31553387 = 31553398
29 + 31553369 = 31553398
47 + 31553351 = 31553398
59 + 31553339 = 31553398
137 + 31553261 = 31553398
179 + 31553219 = 31553398
197 + 31553201 = 31553398
479 + 31552919 = 31553398

Showing the first eight; more decompositions exist.
