Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561240, here are decompositions:

11 + 561229 = 561240
41 + 561199 = 561240
59 + 561181 = 561240
67 + 561173 = 561240
79 + 561161 = 561240
131 + 561109 = 561240
137 + 561103 = 561240
139 + 561101 = 561240

Showing the first eight; more decompositions exist.
