Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554032, here are decompositions:

19 + 31554013 = 31554032
199 + 31553833 = 31554032
229 + 31553803 = 31554032
271 + 31553761 = 31554032
313 + 31553719 = 31554032
373 + 31553659 = 31554032
673 + 31553359 = 31554032
1033 + 31552999 = 31554032

Showing the first eight; more decompositions exist.
