Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561020, here are decompositions:

43 + 560977 = 561020
79 + 560941 = 561020
127 + 560893 = 561020
151 + 560869 = 561020
157 + 560863 = 561020
193 + 560827 = 561020
223 + 560797 = 561020
283 + 560737 = 561020

Showing the first eight; more decompositions exist.
