Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554006, here are decompositions:

13 + 31553993 = 31554006
19 + 31553987 = 31554006
23 + 31553983 = 31554006
103 + 31553903 = 31554006
139 + 31553867 = 31554006
173 + 31553833 = 31554006
199 + 31553807 = 31554006
223 + 31553783 = 31554006

Showing the first eight; more decompositions exist.
