Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553056, here are decompositions:

113 + 31552943 = 31553056
137 + 31552919 = 31553056
149 + 31552907 = 31553056
173 + 31552883 = 31553056
239 + 31552817 = 31553056
347 + 31552709 = 31553056
467 + 31552589 = 31553056
503 + 31552553 = 31553056

Showing the first eight; more decompositions exist.
