Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561338, here are decompositions:

31 + 561307 = 561338
61 + 561277 = 561338
109 + 561229 = 561338
139 + 561199 = 561338
157 + 561181 = 561338
229 + 561109 = 561338
241 + 561097 = 561338
277 + 561061 = 561338

Showing the first eight; more decompositions exist.
