Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561180, here are decompositions:

7 + 561173 = 561180
19 + 561161 = 561180
71 + 561109 = 561180
79 + 561101 = 561180
83 + 561097 = 561180
89 + 561091 = 561180
97 + 561083 = 561180
101 + 561079 = 561180

Showing the first eight; more decompositions exist.
