Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561968, here are decompositions:

7 + 561961 = 561968
37 + 561931 = 561968
61 + 561907 = 561968
139 + 561829 = 561968
181 + 561787 = 561968
409 + 561559 = 561968
439 + 561529 = 561968
601 + 561367 = 561968

Showing the first eight; more decompositions exist.
