Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550644, here are decompositions:

7 + 550637 = 550644
13 + 550631 = 550644
23 + 550621 = 550644
37 + 550607 = 550644
67 + 550577 = 550644
103 + 550541 = 550644
113 + 550531 = 550644
131 + 550513 = 550644

Showing the first eight; more decompositions exist.
