Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561562, here are decompositions:

3 + 561559 = 561562
11 + 561551 = 561562
41 + 561521 = 561562
101 + 561461 = 561562
173 + 561389 = 561562
311 + 561251 = 561562
389 + 561173 = 561562
401 + 561161 = 561562

Showing the first eight; more decompositions exist.
