Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561946, here are decompositions:

3 + 561943 = 561946
23 + 561923 = 561946
29 + 561917 = 561946
107 + 561839 = 561946
137 + 561809 = 561946
149 + 561797 = 561946
179 + 561767 = 561946
233 + 561713 = 561946

Showing the first eight; more decompositions exist.
