Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553038, here are decompositions:

17 + 31553021 = 31553038
131 + 31552907 = 31553038
191 + 31552847 = 31553038
311 + 31552727 = 31553038
317 + 31552721 = 31553038
449 + 31552589 = 31553038
617 + 31552421 = 31553038
809 + 31552229 = 31553038

Showing the first eight; more decompositions exist.
