Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561248, here are decompositions:

19 + 561229 = 561248
67 + 561181 = 561248
139 + 561109 = 561248
151 + 561097 = 561248
157 + 561091 = 561248
229 + 561019 = 561248
271 + 560977 = 561248
307 + 560941 = 561248

Showing the first eight; more decompositions exist.
