Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561326, here are decompositions:

13 + 561313 = 561326
19 + 561307 = 561326
97 + 561229 = 561326
127 + 561199 = 561326
223 + 561103 = 561326
229 + 561097 = 561326
307 + 561019 = 561326
349 + 560977 = 561326

Showing the first eight; more decompositions exist.
