Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561098, here are decompositions:

7 + 561091 = 561098
19 + 561079 = 561098
37 + 561061 = 561098
79 + 561019 = 561098
157 + 560941 = 561098
211 + 560887 = 561098
229 + 560869 = 561098
271 + 560827 = 561098

Showing the first eight; more decompositions exist.
