Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561396, here are decompositions:

7 + 561389 = 561396
19 + 561377 = 561396
23 + 561373 = 561396
29 + 561367 = 561396
37 + 561359 = 561396
53 + 561343 = 561396
83 + 561313 = 561396
89 + 561307 = 561396

Showing the first eight; more decompositions exist.
