Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554152, here are decompositions:

31 + 31554121 = 31554152
79 + 31554073 = 31554152
109 + 31554043 = 31554152
139 + 31554013 = 31554152
349 + 31553803 = 31554152
433 + 31553719 = 31554152
769 + 31553383 = 31554152
919 + 31553233 = 31554152

Showing the first eight; more decompositions exist.
