Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561204, here are decompositions:

5 + 561199 = 561204
13 + 561191 = 561204
23 + 561181 = 561204
31 + 561173 = 561204
43 + 561161 = 561204
101 + 561103 = 561204
103 + 561101 = 561204
107 + 561097 = 561204

Showing the first eight; more decompositions exist.
