Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554150, here are decompositions:

7 + 31554143 = 31554150
29 + 31554121 = 31554150
73 + 31554077 = 31554150
107 + 31554043 = 31554150
137 + 31554013 = 31554150
139 + 31554011 = 31554150
157 + 31553993 = 31554150
163 + 31553987 = 31554150

Showing the first eight; more decompositions exist.
