Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561756, here are decompositions:

23 + 561733 = 561756
43 + 561713 = 561756
53 + 561703 = 561756
89 + 561667 = 561756
149 + 561607 = 561756
157 + 561599 = 561756
197 + 561559 = 561756
227 + 561529 = 561756

Showing the first eight; more decompositions exist.
