Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561678, here are decompositions:

11 + 561667 = 561678
71 + 561607 = 561678
79 + 561599 = 561678
127 + 561551 = 561678
149 + 561529 = 561678
157 + 561521 = 561678
239 + 561439 = 561678
269 + 561409 = 561678

Showing the first eight; more decompositions exist.
