Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561042, here are decompositions:

23 + 561019 = 561042
73 + 560969 = 561042
101 + 560941 = 561042
103 + 560939 = 561042
113 + 560929 = 561042
149 + 560893 = 561042
151 + 560891 = 561042
173 + 560869 = 561042

Showing the first eight; more decompositions exist.
