Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553068, here are decompositions:

5 + 31553063 = 31553068
47 + 31553021 = 31553068
149 + 31552919 = 31553068
251 + 31552817 = 31553068
347 + 31552721 = 31553068
359 + 31552709 = 31553068
479 + 31552589 = 31553068
647 + 31552421 = 31553068

Showing the first eight; more decompositions exist.
