Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554650, here are decompositions:

13 + 31554637 = 31554650
19 + 31554631 = 31554650
31 + 31554619 = 31554650
37 + 31554613 = 31554650
67 + 31554583 = 31554650
79 + 31554571 = 31554650
109 + 31554541 = 31554650
139 + 31554511 = 31554650

Showing the first eight; more decompositions exist.
