Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561266, here are decompositions:

37 + 561229 = 561266
67 + 561199 = 561266
157 + 561109 = 561266
163 + 561103 = 561266
337 + 560929 = 561266
373 + 560893 = 561266
379 + 560887 = 561266
397 + 560869 = 561266

Showing the first eight; more decompositions exist.
