Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561284, here are decompositions:

7 + 561277 = 561284
103 + 561181 = 561284
181 + 561103 = 561284
193 + 561091 = 561284
223 + 561061 = 561284
307 + 560977 = 561284
397 + 560887 = 561284
421 + 560863 = 561284

Showing the first eight; more decompositions exist.
