Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561158, here are decompositions:

61 + 561097 = 561158
67 + 561091 = 561158
79 + 561079 = 561158
97 + 561061 = 561158
139 + 561019 = 561158
181 + 560977 = 561158
229 + 560929 = 561158
271 + 560887 = 561158

Showing the first eight; more decompositions exist.
