Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554084, here are decompositions:

7 + 31554077 = 31554084
11 + 31554073 = 31554084
41 + 31554043 = 31554084
71 + 31554013 = 31554084
73 + 31554011 = 31554084
97 + 31553987 = 31554084
101 + 31553983 = 31554084
181 + 31553903 = 31554084

Showing the first eight; more decompositions exist.
