Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561066, here are decompositions:

5 + 561061 = 561066
7 + 561059 = 561066
13 + 561053 = 561066
19 + 561047 = 561066
47 + 561019 = 561066
89 + 560977 = 561066
97 + 560969 = 561066
127 + 560939 = 561066

Showing the first eight; more decompositions exist.
