Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561272, here are decompositions:

43 + 561229 = 561272
73 + 561199 = 561272
163 + 561109 = 561272
181 + 561091 = 561272
193 + 561079 = 561272
211 + 561061 = 561272
331 + 560941 = 561272
379 + 560893 = 561272

Showing the first eight; more decompositions exist.
