Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561088, here are decompositions:

5 + 561083 = 561088
29 + 561059 = 561088
41 + 561047 = 561088
149 + 560939 = 561088
191 + 560897 = 561088
197 + 560891 = 561088
251 + 560837 = 561088
317 + 560771 = 561088

Showing the first eight; more decompositions exist.
