Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561126, here are decompositions:

17 + 561109 = 561126
23 + 561103 = 561126
29 + 561097 = 561126
43 + 561083 = 561126
47 + 561079 = 561126
67 + 561059 = 561126
73 + 561053 = 561126
79 + 561047 = 561126

Showing the first eight; more decompositions exist.
