Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561150, here are decompositions:

41 + 561109 = 561150
47 + 561103 = 561150
53 + 561097 = 561150
59 + 561091 = 561150
67 + 561083 = 561150
71 + 561079 = 561150
89 + 561061 = 561150
97 + 561053 = 561150

Showing the first eight; more decompositions exist.
