Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561426, here are decompositions:

7 + 561419 = 561426
17 + 561409 = 561426
37 + 561389 = 561426
53 + 561373 = 561426
59 + 561367 = 561426
67 + 561359 = 561426
79 + 561347 = 561426
83 + 561343 = 561426

Showing the first eight; more decompositions exist.
