Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553252, here are decompositions:

19 + 31553233 = 31553252
163 + 31553089 = 31553252
373 + 31552879 = 31553252
421 + 31552831 = 31553252
571 + 31552681 = 31553252
613 + 31552639 = 31553252
631 + 31552621 = 31553252
673 + 31552579 = 31553252

Showing the first eight; more decompositions exist.
