Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561308, here are decompositions:

31 + 561277 = 561308
79 + 561229 = 561308
109 + 561199 = 561308
127 + 561181 = 561308
199 + 561109 = 561308
211 + 561097 = 561308
229 + 561079 = 561308
331 + 560977 = 561308

Showing the first eight; more decompositions exist.
