Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561722, here are decompositions:

19 + 561703 = 561722
163 + 561559 = 561722
193 + 561529 = 561722
283 + 561439 = 561722
313 + 561409 = 561722
349 + 561373 = 561722
379 + 561343 = 561722
409 + 561313 = 561722

Showing the first eight; more decompositions exist.
