Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561254, here are decompositions:

3 + 561251 = 561254
73 + 561181 = 561254
151 + 561103 = 561254
157 + 561097 = 561254
163 + 561091 = 561254
193 + 561061 = 561254
277 + 560977 = 561254
313 + 560941 = 561254

Showing the first eight; more decompositions exist.
