Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561056, here are decompositions:

3 + 561053 = 561056
37 + 561019 = 561056
79 + 560977 = 561056
127 + 560929 = 561056
163 + 560893 = 561056
193 + 560863 = 561056
229 + 560827 = 561056
337 + 560719 = 561056

Showing the first eight; more decompositions exist.
