Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554054, here are decompositions:

11 + 31554043 = 31554054
41 + 31554013 = 31554054
43 + 31554011 = 31554054
61 + 31553993 = 31554054
67 + 31553987 = 31554054
71 + 31553983 = 31554054
151 + 31553903 = 31554054
251 + 31553803 = 31554054

Showing the first eight; more decompositions exist.
