Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554308, here are decompositions:

67 + 31554241 = 31554308
109 + 31554199 = 31554308
127 + 31554181 = 31554308
547 + 31553761 = 31554308
601 + 31553707 = 31554308
691 + 31553617 = 31554308
1231 + 31553077 = 31554308
1291 + 31553017 = 31554308

Showing the first eight; more decompositions exist.
