Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561318, here are decompositions:

5 + 561313 = 561318
11 + 561307 = 561318
41 + 561277 = 561318
67 + 561251 = 561318
89 + 561229 = 561318
127 + 561191 = 561318
137 + 561181 = 561318
157 + 561161 = 561318

Showing the first eight; more decompositions exist.
