Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561546, here are decompositions:

17 + 561529 = 561546
107 + 561439 = 561546
127 + 561419 = 561546
137 + 561409 = 561546
157 + 561389 = 561546
173 + 561373 = 561546
179 + 561367 = 561546
199 + 561347 = 561546

Showing the first eight; more decompositions exist.
