Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561152, here are decompositions:

43 + 561109 = 561152
61 + 561091 = 561152
73 + 561079 = 561152
211 + 560941 = 561152
223 + 560929 = 561152
283 + 560869 = 561152
349 + 560803 = 561152
433 + 560719 = 561152

Showing the first eight; more decompositions exist.
