Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553372, here are decompositions:

3 + 31553369 = 31553372
13 + 31553359 = 31553372
139 + 31553233 = 31553372
211 + 31553161 = 31553372
283 + 31553089 = 31553372
373 + 31552999 = 31553372
541 + 31552831 = 31553372
691 + 31552681 = 31553372

Showing the first eight; more decompositions exist.
