Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561256, here are decompositions:

5 + 561251 = 561256
83 + 561173 = 561256
173 + 561083 = 561256
197 + 561059 = 561256
317 + 560939 = 561256
359 + 560897 = 561256
383 + 560873 = 561256
419 + 560837 = 561256

Showing the first eight; more decompositions exist.
