Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554644, here are decompositions:

3 + 31554641 = 31554644
7 + 31554637 = 31554644
13 + 31554631 = 31554644
31 + 31554613 = 31554644
61 + 31554583 = 31554644
73 + 31554571 = 31554644
103 + 31554541 = 31554644
127 + 31554517 = 31554644

Showing the first eight; more decompositions exist.
