Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505644, here are decompositions:

5 + 505639 = 505644
11 + 505633 = 505644
31 + 505613 = 505644
37 + 505607 = 505644
43 + 505601 = 505644
71 + 505573 = 505644
107 + 505537 = 505644
131 + 505513 = 505644

Showing the first eight; more decompositions exist.
