Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561298, here are decompositions:

47 + 561251 = 561298
107 + 561191 = 561298
137 + 561161 = 561298
197 + 561101 = 561298
239 + 561059 = 561298
251 + 561047 = 561298
359 + 560939 = 561298
401 + 560897 = 561298

Showing the first eight; more decompositions exist.
