Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554162, here are decompositions:

19 + 31554143 = 31554162
41 + 31554121 = 31554162
89 + 31554073 = 31554162
149 + 31554013 = 31554162
151 + 31554011 = 31554162
179 + 31553983 = 31554162
359 + 31553803 = 31554162
379 + 31553783 = 31554162

Showing the first eight; more decompositions exist.
