Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554044, here are decompositions:

31 + 31554013 = 31554044
61 + 31553983 = 31554044
211 + 31553833 = 31554044
241 + 31553803 = 31554044
283 + 31553761 = 31554044
337 + 31553707 = 31554044
373 + 31553671 = 31554044
541 + 31553503 = 31554044

Showing the first eight; more decompositions exist.
