Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561290, here are decompositions:

13 + 561277 = 561290
61 + 561229 = 561290
109 + 561181 = 561290
181 + 561109 = 561290
193 + 561097 = 561290
199 + 561091 = 561290
211 + 561079 = 561290
229 + 561061 = 561290

Showing the first eight; more decompositions exist.
