Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561142, here are decompositions:

41 + 561101 = 561142
59 + 561083 = 561142
83 + 561059 = 561142
89 + 561053 = 561142
173 + 560969 = 561142
251 + 560891 = 561142
269 + 560873 = 561142
359 + 560783 = 561142

Showing the first eight; more decompositions exist.
