Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561966, here are decompositions:

5 + 561961 = 561966
19 + 561947 = 561966
23 + 561943 = 561966
43 + 561923 = 561966
59 + 561907 = 561966
127 + 561839 = 561966
137 + 561829 = 561966
157 + 561809 = 561966

Showing the first eight; more decompositions exist.
