Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561026, here are decompositions:

7 + 561019 = 561026
97 + 560929 = 561026
139 + 560887 = 561026
157 + 560869 = 561026
163 + 560863 = 561026
199 + 560827 = 561026
223 + 560803 = 561026
229 + 560797 = 561026

Showing the first eight; more decompositions exist.
