Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561320, here are decompositions:

7 + 561313 = 561320
13 + 561307 = 561320
43 + 561277 = 561320
139 + 561181 = 561320
211 + 561109 = 561320
223 + 561097 = 561320
229 + 561091 = 561320
241 + 561079 = 561320

Showing the first eight; more decompositions exist.
