Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561420, here are decompositions:

11 + 561409 = 561420
31 + 561389 = 561420
43 + 561377 = 561420
47 + 561373 = 561420
53 + 561367 = 561420
61 + 561359 = 561420
73 + 561347 = 561420
107 + 561313 = 561420

Showing the first eight; more decompositions exist.
