Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553462, here are decompositions:

79 + 31553383 = 31553462
103 + 31553359 = 31553462
229 + 31553233 = 31553462
373 + 31553089 = 31553462
463 + 31552999 = 31553462
571 + 31552891 = 31553462
631 + 31552831 = 31553462
769 + 31552693 = 31553462

Showing the first eight; more decompositions exist.
