Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554108, here are decompositions:

31 + 31554077 = 31554108
97 + 31554011 = 31554108
241 + 31553867 = 31554108
307 + 31553801 = 31554108
331 + 31553777 = 31554108
347 + 31553761 = 31554108
349 + 31553759 = 31554108
379 + 31553729 = 31554108

Showing the first eight; more decompositions exist.
