Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554624, here are decompositions:

5 + 31554619 = 31554624
7 + 31554617 = 31554624
11 + 31554613 = 31554624
41 + 31554583 = 31554624
53 + 31554571 = 31554624
83 + 31554541 = 31554624
97 + 31554527 = 31554624
107 + 31554517 = 31554624

Showing the first eight; more decompositions exist.
