Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561038, here are decompositions:

19 + 561019 = 561038
61 + 560977 = 561038
97 + 560941 = 561038
109 + 560929 = 561038
151 + 560887 = 561038
211 + 560827 = 561038
241 + 560797 = 561038
271 + 560767 = 561038

Showing the first eight; more decompositions exist.
